Allakhverdiev SI, Zharmukhamedov SK, Rodionova MV, Shuvalov VA, Dismukes C, Shen J-R, Barber J, Samuelsson G, Govindjeeet al., 2017, Vyacheslav (Slava) Klimov (1945-2017): A scientist par excellence, a great human being, a friend, and a Renaissance man., Photosynth Res

Vyacheslav Vasilevich (V.V.) Klimov (or Slava, as most of us called him) was born on January 12, 1945 and passed away on May 9, 2017. He began his scientific career at the Bach Institute of Biochemistry of the USSR Academy of Sciences (Akademy Nauk (AN) SSSR), Moscow, Russia, and then, he was associated with the Institute of Photosynthesis, Pushchino, Moscow Region, for about 50 years. He worked in the field of biochemistry and biophysics of photosynthesis. He is known for his studies on the molecular organization of photosystem II (PSII). He was an eminent scientist in the field of photobiology, a well-respected professor, and, above all, an outstanding researcher. Further, he was one of the founding members of the Institute of Photosynthesis in Pushchino, Russia. To most, Slava Klimov was a great human being. He was one of the pioneers of research on the understanding of the mechanism of light energy conversion and of water oxidation in photosynthesis. Slava had many collaborations all over the world, and he is (and will be) very much missed by the scientific community and friends in Russia as well as around the World. We present here a brief biography and some comments on his research in photosynthesis. We remember him as a friendly and enthusiastic person who had an unflagging curiosity and energy to conduct outstanding research in many aspects of photosynthesis, especially that related to PSII.

© 2017 [Figure presented]James Barber is Emeritus Ernst Chain Professor of Biochemistry, Senior Research Fellow at Imperial College London, and the Cannon Visiting Professor to Nanyang Technological University (NTU) in Singapore. He is a Fellow of the Royal Society (FRS), Fellow of the Royal Society of Chemistry (FRSC), Member of European Academy, and Foreign Member of the Swedish Royal Academy of Sciences. He has Honorary Doctorates of Stockholm University, University of East Anglia, and NTU. He has been awarded several medals and prizes including Flintoff Medal of RSC, Novartis Medal (UK Biochemical Society), Wheland Medal (University of Chicago), Eni-Ital gas/ENI Prize, Interdisciplinary Prize Medal of the RSC, Porter Medal of the International Photochemical Societies (Europe, USA, and Asia), and the Communication Award of the International Society of Photosynthesis Research. In 2009 he was the Lee Kuan Yew Di stinguished Visitor to Singapore. Much of his research has focused on PSII and the water-splitting process that it catalyzes, and its crystal structure obtained in 2004. He is now investigating inorganic systems to mimic PSII in order to develop technology for non-polluting solar fuels. Photosynthesis stores solar energy in the form of chemical bonds. The very first chemical reaction is the splitting of H 2 O into dioxygen and hydrogen equivalent. The high energy of the latter is used to reduce CO 2 to the organic molecules of life and is the origin of our fossil fuels. The question is: can we mimic this natural process as a large-scale renewable energy technology to address the challenges of the 2015 Paris Agreement on Climate Change (COP21)?

Barber J, 2017, Photosynthetic water splitting by the Mn4Ca2+OX catalyst of photosystem II: its structure, robustness and mechanism., Q Rev Biophys, Vol: 50

The biological energy cycle of our planet is driven by photosynthesis whereby sunlight is absorbed by chlorophyll and other accessory pigments. The excitation energy is then efficiently transferred to a reaction centre where charge separation occurs in a few picoseconds. In the case of photosystem II (PSII), the energy of the charge transfer state is used to split water into oxygen and reducing equivalents. This is accomplished by the relatively low energy content of four photons of visible light. PSII is a large multi-subunit membrane protein complex embedded in the lipid environment of the thylakoid membranes of plants, algae and cyanobacteria. Four high energy electrons, together with four protons (4H+), are used to reduce plastoquinone (PQ), the terminal electron acceptor of PSII, to plastoquinol (PQH2). PQH2 passes its reducing equivalents to an electron transfer chain which feeds into photosystem I (PSI) where they gain additional reducing potential from a second light reaction which is necessary to drive CO2 reduction. The catalytic centre of PSII consists of a cluster of four Mn ions and a Ca2+ linked by oxo bonds. In addition, there are seven amino acid ligands. In this Article, I discuss the structure of this metal cluster, its stability and the probability that an acid-base (nucleophilic-electrophilic) mechanism catalyses the water splitting reaction on the surface of the metal-cluster. Evidence for this mechanism is presented from studies on water splitting catalysts consisting of organo-complexes of ruthenium and manganese and also by comparison with the enzymology of carbon monoxide dehydrogenase (CODH). Finally the relevance of our understanding of PSII is discussed in terms of artificial photosynthesis with emphasis on inorganic water splitting catalysts as oxygen generating photoelectrodes.
