Rethinking corporate value: A conversation with Yoshimitsu Kobayashi

November 8, 2019

Kaiteki “the sustainable well-being of people, society and planet Earth,” is fundamental to the identity of the Mitsubishi Chemical Holdings Corporation and the KAITEKI Institute, MCHC’s think tank and research institute. The concept aligns seamlessly with the goals of Arizona State University’s Global Futures Laboratory, which seeks to shape a future in which Earth and all its inhabitants can thrive. ASU and MCHC have partnered to support research aimed at realizing the concept of kaiteki through the Global KAITEKI Center.

MCHC Chairman Yoshimitsu Kobayashi visited ASU on Oct. 24 to kick off the center’s activities. At the event, Kobayashi and ASU President Michael Crow shared their visions for a sustainable future, and the two organizations pledged to work together to advance these goals.

Here, Kobayashi explains kaiteki management, how it can be applied, and why partnerships between industry and academia are essential to achieving this ambitious vision.

Question: How do you explain kaiteki to others?

Answer: The Japanese word kaiteki means “comfort” or “well-being,” and I firmly believe that it’s the most appropriate name for the type of value sought by a company with Japanese origins. The forms of value provided by Mitsubishi Chemical Holdings are separated onto three axes: the economics axis, which indicates profits and efficiency; the technology axis, which indicates innovation and new frontiers; and the sustainability axis, which indicates contributions to public interest and the environment. We quantitatively measure and assess the values along each axis, increasing all three in a balanced way. We call this kaiteki value.

Q: How did kaiteki become a driving principle for MCHC?

A: When I became CEO in 2007, I felt strongly that the company’s almost total lack of an established corporate identity was very risky. Unlike beer or car manufacturers, we’re engaged in a diverse range of businesses — spanning everything from pharmaceuticals by the milligram to petrochemicals by the ton — and it’s difficult to explain what kind of company we are in simple terms.

So, in 2007 I made sustainability, health and comfort our decision criteria, as well as our slogan, and I established as company policy that we would undertake business activities in line with these criteria in order to solve problems faced by society, including the problem of carbon dioxide emissions, and to help people live more comfortable lives. We then carefully considered this policy in connection with our market capitalization, intrinsic corporate value and general existential value.

We concluded that value formed on three axes — Management of Economics, Management of Technology and Management of Sustainability — would itself constitute our corporate value. In 2011, we began to refer to corporate value generated on these three axes as “Kaiteki Management.” Everyone in the Mitsubishi Chemical Holdings Group, both inside and outside Japan, comes together and pursues all corporate activities under the kaiteki banner; this is our identity.

Q: Why is kaiteki so very important in today’s world?

A: Humanity currently faces a number of pressing challenges, including climate change and marine plastic pollution. In light of these challenges, which pertain to Management of Sustainability, corporations that are greedy in pursuing profit alone will not last long. We believe we can achieve sustainable growth by employing technology and innovation to provide solutions to social and environmental issues — Management of Technology — and thereby increase business income — Management of Economics — which is none other than the pursuit of what we call kaiteki value.

In August of this year, the Business Roundtable, an association led by major U.S. companies, announced its departure from the shareholder supremacy principle. The time has come for the world to rethink the meaning of corporate value. We believe our decision in 2011 to institute Kaiteki Management was appropriate to the age in which we live.

Q: How do you envision kaiteki applied in business?

A: Realizing kaiteki value in business means undertaking business activities that lead to sustained growth while solving social issues. This encompasses energy-generating solutions like organic solar cells, energy-storage solutions such as lithium-ion battery materials, and energy-saving solutions such as carbon fiber-reinforced plastics and gallium nitride, as well as solutions related to health and living such as regenerative medicine and new forms of agribusiness — though these businesses are still in the maturation process.

In connection with communities, we have declared our support for the Task Force on Climate-Related Financial Disclosures, and we participate in the Alliance to End Plastic Waste (AEPW) and the Ellen MacArthur Foundation’s Circular Economy 100 Network. We also chair the Carbon Recycle Fund, an association of private-sector companies, as a part of our participation in government efforts to expand the circular economy, as well as the government-sponsored Japan Initiative for Marine Environment, which is tasked with addressing the problem of plastic waste.

Q: Why are partnerships important to advancing this vision?

A: Climate change and marine plastic pollution are global challenges that go beyond national borders. And with ICT and other technologies growing more sophisticated and information becoming widely available, society in general is demanding that problems be solved with considerable speed.

In light of this, companies and research institutes have neither the time nor resources to handle the entire process from crafting a vision to seeing it through all on their own. To provide the value that society requires in a way that is timely and precise, it is becoming all the more important to combine the scholarly perspective of the academy with the business perspective of the private sector in the form of open innovation.

Q: Why did you decide to partner with ASU? 

A: I owe a debt of gratitude to ASU’s Dr. George Stephanopoulos for this partnership. He has been a good friend of mine since he served for two years as CTO of Mitsubishi Chemical Holdings from the year 2000, and I have often discussed Kaiteki Management with him.

In addition, under the leadership of President Crow, ASU has emphasized education and research that strongly promotes innovation, established the expectation that achievements contribute to the public interest, and acquired a track record in actively pursuing collaborations between industry and academia that pivot on sustainability. We believed that these factors will help create synergies for realizing the kaiteki that we have proposed and pursued.

Q: How will working with ASU and the Global KAITEKI Center support kaiteki and building a sustainable future?

A: We have high expectations, in particular for ASU’s Julie Ann Wrigley Global Institute of Sustainability and the new Global Futures Laboratory. I firmly believe that joining our kaiteki concept with ASU’s sustainability-focused technology, research capabilities and sophisticated social scientific perspectives will make it possible to create new methodologies and roadmaps.

Q: If a company wanted to realize kaiteki, how should they begin?

A: I think it is first important that all stakeholders, including shareholders, customers, employees and the general public, recognize the meaning and importance of kaiteki value. Deepening communication with stakeholders and providing society with solutions through the products and services that result from this communication will generate kaiteki value.

Q: What three key things need to happen in order to realize kaiteki world-wide?

A: The kaiteki vision needs to be shared with shareholders, employees, customers and other stakeholders worldwide.

Management of Sustainability, one of the three axes of Kaiteki Management, needs to be visualized, quantified and standardized, even while 80% of the focus may remain on Management of Economics.

In addition, alliances need to be promoted between companies and universities for the purpose of creating kaiteki value — as is the case with ASU.

Q: What legacy do you want to leave on the world?

A: Kaiteki is a beautiful Japanese word that means “comfort” or “well-being,” and ever since founding the KAITEKI Institute, my dream has been to make that word as familiar as “kaizen” or “teriyaki” all over the world. Another goal is to visualize and quantify Management of Sustainability value and to standardize it as an important assessment indicator alongside economic value. I believe this would significantly change how corporate activities are assessed and judged.

Photosynthesis seen in a new light by rapid X-ray pulses

November 8, 2019

The ability to transform sunlight into energy is one of nature’s more remarkable feats. Scientists understand the basic process of photosynthesis, but many crucial details remain elusive, occurring at dimensions and fleeting time scales long deemed too minuscule to probe.

Now, that is changing. This graphic shows the basic design of an X-ray free electron laser or XFEL, in which brilliant X-ray bursts strike crystallized samples, causing diffraction patterns that can be reassembled into detailed images. X-rays damage biomolecules, a problem that has plagued structure determination efforts for decades. But the X-ray bursts produced by an XFEL are so short — lasting mere femtoseconds — that X-ray scattering from a molecule can be recorded before destruction takes place, akin to using a fast camera shutter.

In a new study led by Petra Fromme and Nadia Zatsepin at the Biodesign Center for Applied Structural Discovery, the School of Molecular Sciences and the Department of Physics at Arizona State University, researchers investigated the structure of Photosystem I (PSI) with ultrashort X-ray pulses at the European X-ray Free Electron Laser (EuXFEL) in Hamburg, Germany.

PSI is a large biomolecular system that acts as a large converter transforming solar energy into chemical energy. Photosynthesis provides energy for all complex life on Earth and supplies the oxygen we breathe. Advances in unraveling the secrets of photosynthesis promise to improve agriculture and aid in the development of next-generation solar energy storage systems that combine the efficiency of nature with the stability of human-engineered systems.

“This work is so important, as it shows the first proof of concept of megahertz serial crystallography with one of the largest and most complex membrane proteins in photosynthesis: Photosystem I,” said Fromme. “The work paves the way towards time-resolved studies at the EuXFEL to determine molecular movies of the light-driven path of the electrons in photosynthesis or to visualize how cancer drugs attack malfunctioning proteins.”

The EuXFEL, which recently began operation, is the first to employ a superconducting linear accelerator that yields exciting new capabilities including very fast megahertz repetition rates of its X-ray pulses — over 9,000 times faster than any other XFEL — with pulses separated by less than one-millionth of a second. With these incredibly brief bursts of X-ray light, researchers will be able to much more quickly record molecular movies of fundamental biological processes and will likely impact diverse fields including medicine and pharmacology, chemistry, physics, materials science, energy research, environmental studies, electronics, nanotechnology and photonics. Fromme and Zatsepin are co-corresponding authors of the paper, published in the current issue of the journal Nature Communications.

Strength in numbers

Petra Fromme

Fromme is the director of the Biodesign Center for Applied Structural Discovery (CASD) and leads the experimental team efforts of the project, while Zatsepin led the XFEL data analysis team.

“This is a significant milestone in the development of serial femtosecond crystallography, building on the well-coordinated effort of a large, cross-disciplinary, international team and years of developments in disparate fields,” said Zatsepin, former research assistant professor in the ASU Department of Physics and Biodesign CASD, and now senior research fellow at La Trobe University in Australia.

Christopher Gisriel, the paper’s co-first author, worked on the project while a postdoctoral researcher in the Fromme laboratory and is excited about the project.

“Fast data collection in serial femtosecond crystallography experiments makes this revolutionary technique more accessible to those interested in the structure-function relationship for enzymes. This is exemplified by our new publication in Nature Communications showing that even the most difficult and complex protein structures can be solved by serial femtosecond crystallography while collecting data at megahertz repetition rate.”

“It is very exciting to see the hard work from the many folks that drove this project to materialize,” said Jesse Coe, co-first author who graduated last year with a PhD in biochemistry from ASU. “This is a huge step in the right direction toward better understanding nature’s process of electron transfer that has been refined over billions of years.”

Extreme science

An XFEL (for X-ray free-electron laser) delivers X-ray light that is a billion times brighter than conventional X-ray sources. The brilliant, laser-like X-ray pulses are produced by electrons accelerated to near light speed and fed through the gap between series of alternating magnets, a device known as an undulator. The undulator forces the electrons to jiggle and bunch up into discrete packages. Each of the perfectly synchronized wiggling electron bunches emits a powerful, brief X-ray pulse along the electron flight path.

In serial femtosecond crystallography, a jet of protein crystals is injected into the path of the pulsed XFEL beam at room temperature, yielding structural information in the form of diffraction patterns. From these patterns, scientists can determine atomic-scale images of proteins in close-to-native conditions, paving the way toward accurate molecular movies of molecules at work.

X-rays damage biomolecules, a problem that has plagued structure determination efforts for decades, requiring the biomolecules to be frozen to limit the damage. But the X-ray bursts produced by an XFEL are so short — lasting mere femtoseconds — that X-ray scattering from a molecule can be recorded before destruction takes place, akin to using a fast camera shutter. As a point of reference, a femtosecond is a millionth of a billionth of a second, the same ratio as a second is to 32 million years. 

Due to the sophistication, size and cost of XFEL facilities, only five are currently available for such experiments worldwide — a severe bottleneck for researchers since each XFEL can typically only host one experiment at a time. Most XFELs generate X-ray pulses between 30 and 120 times per second, and it can take several hours to days to collect the data required to determine a single structure, let alone a series of frames in a molecular movie. The EuXFEL is the first to employ a superconducting linear accelerator in its design, enabling the fastest succession of X-ray pulses of any XFEL, which can significantly reduce the time it takes to determine each structure or frame of the movie.

High risk, high reward

Nadia Zatsepin

Because the sample is obliterated by the intense X-ray pulses, it must be replenished in time for the next X-ray pulse, which required PSI crystals to be delivered 9,000 times faster at the EuXFEL than at earlier XFELs — at a jet speed of about 50 meters per second (160 feet per second), like a microfluidic fire hose. This was challenging as it requires large amounts of the precious protein contained within uniform crystals to reach these high jet speeds and avoid blocking the sample delivery system. Large membrane proteins are so difficult to isolate, crystallize and deliver to the beam, that it wasn’t known if this important class of proteins could be studied at the EuXFEL.

The team developed new methods that allowed PSI, which is a large complex consisting of 36 proteins and 381 cofactors, that include the 288 chlorophylls (the green pigments that absorb the light) and has over 150,000 atoms and is more than 20 times larger than previous proteins studied at the EuXFEL, to have its structure determined at room temperature to a remarkable 2.9 angstrom resolution — a significant milestone.

Billions of microcrystals of the PSI membrane protein, derived from cyanobacteria, had to be grown for the new study. Rapid crystal growth from nanocrystal seeds was required to guarantee the essential uniformity of crystal size and shape. PSI is a membrane protein, which is a class of proteins of high importance that have been notoriously tricky to characterize. Their elaborate structures are embedded in the cell membrane’s lipid bilayer. Typically, they must be carefully isolated in fully active form from their native environment and transformed into a crystalline state, where the molecules pack into crystals but maintain all their native function.

In the case of PSI, this is achieved by extracting it with very mild detergents that replace the membrane and surround the protein like a pool inner tube, which mimics the native membrane environment and keeps PSI fully functional once it’s packed within the crystals. So when researchers shine light on the green pigments (chlorophylls) that catch the light by the antenna system of PSI, the energy is used to shoot an electron across the membrane.

To keep PSI fully functional, the crystals are only weakly packed containing 78% water, which makes them soft like a piece of butter in the sun and makes it difficult handling these fragile crystals.

“To isolate, characterize and crystallize one gram of PSI, or one billion billion PSI molecules, for the experiments in their fully active form was a huge effort of the students and researchers in my team,” says Fromme. “In the future, with even higher repetition rates and novel sample delivery systems, the sample consumption will be dramatically reduced.”

The recording and analysis of the diffraction data was another challenge. A unique X-ray detector was developed by the EuXFEL and DESY to handle the demands of structural biology studies at the EuXFEL: the adaptive-gain integrating pixel detector, or AGIPD. Each of AGIPD’s 1 million pixels are less than a hundredth of an inch across and contain 352 analog memory cells, which enable the AGIPD to collect data at megahertz rates over a large dynamic range. However, to collect accurate crystallographic data from microcrystals of large membrane proteins required a compromise between spatial resolution and sampling of the data.

“Pushing for higher-resolution data collection with the current detector size could preclude useful processing of the crystallographic data because the diffraction spots are insufficiently resolved by the X-ray detector pixels,” warns Zatsepin, “yet in terms of data rates and dynamic range, what the AGIPD is capable of is incredible.”

The novel data reduction and crystallographic analysis software designed specifically to deal with the challenges unique to the massive data sets in XFEL crystallography — whose development was led by collaborators at CFEL, DESY and ASU — have come a long way since the first high-resolution XFEL experiment in 2011.

“Our software and DESY’s high-performance computing capabilities are really being put to the test with the unprecedented data volumes generated at the EuXFEL. It is always exciting to push the limits of state-of-the-art technology,” Zatsepin says.

Membrane proteins: floppy, yet formidable

Membrane proteins like PSI — named because they are embedded into cell membranes — are vital to all life processes including respiration, nerve function, nutrition uptake and cell-cell signaling. As they are at the surface of each cell they are also the most important pharmaceutical drug targets. More than 60% of all current drugs are targeted to membrane proteins. The design of more effective drugs with fewer side effects is therefore contingent on understanding how particular drugs bind with their target proteins and their highly detailed structural conformations and dynamic activities.

Despite their enormous importance in biology, membrane protein structures make up less than 1% of all protein structures solved to date because they are notoriously tricky to isolate, characterize and crystallize. This is why major advances in crystallographic methods, such as the advent of membrane protein megahertz serial femtosecond crystallography, are undoubtedly going to have a significant impact on the scientific community.

It takes a village

These recent achievements would not be possible without the tireless effort from a dedicated team of nearly 80 researchers from 15 institutions, including ASU, the European XFEL, DESY, the Center for Ultrafast X-ray Science, Hauptman-Woodward Institute, SUNY Buffalo, SLAC, University of Hamburg, University of Goettingen, Hungarian Academy of Sciences, University of Tennessee, Lawrence Livermore National Laboratory, University of Southampton, Hamburg University of Technology and the University of Wisconsin. The research group included U.S. collaborators in the NSF BioXFEL Science and Technology Center and a group of international collaborators, including Adrian P. Mancuso and Romain Letrun, lead scientists at the EuXFEL beamline, and Oleksandr Yefanov and Anton Barty from CFEL/DESY, who worked closely with the ASU team on the complex data analysis.

The ASU team included faculty working at the Biodesign Center for Applied Structural Discovery, the School of Molecular Sciences and the Department of Physics including faculty members John Spence, Richard Kirian, Alexandra Ros and Raimund Fromme. The researchers include co-first authors Chris Gisriel and Jesse Coe, who established the isolation and crystallization of PSI and worked on the data analysis as well as writing of the paper with Petra Fromme, Nadia Zatsepin and all team members. The PSI sample preparation team consisted of Cesar Luna-Chavez, Shatabdi Roy-Chowdhury, Jay-How Yang, Alexander Jones, Jose Domingo Meza, Erin Discianno, Zachary Dobson, James Zook and Jose M. Martin-Garcia. Stella Lisova, Austin Echelmeier, Jorvani Cruz Villarreal, Gerrit Brehm, Marc Messerschmidt and Sabine Botha worked on the sample injection. Natasha E. Stander and Gihan K. Ketawala worked on the data evaluation.

The research was supported in part by the Department of Energy, the National Science Foundation (NSF) Science and Technology Center (STC) BioXFEL award No. STC-1231306 and NSF ABI Innovation award No. 1565180, the National Institutes of Health grant femtosecond crystallography of membrane proteins R01GM095583 and Australian Research Council through the Centre of Excellence in Advanced Molecular Imaging (CE140100011).
