Structure and dynamics of the thylakoid membrane

Jan Mary Anderson FRS (1932-) is a scientist from New Zealand, distinguished by her investigation of photosynthesis. She was the first to show that the photosynthetic mechanism comprises two fundamental components: photosystem I and photosytem II.Anderson is currently an Adjunct Professor at the Australian National University.

Werner Kühlbrandt studied chemistry and crystallography in Berlin, and went on to do his PhD with Nigel Unwin at the MRC Laboratory of Molecular Biology in Cambridge, UK, investigating the structure of two-dimensional ribosome crystals by electron microscopy. He turned to structural studies of membrane proteins as a postdoc, first at the ETH Zürich, and then at Imperial College London. After a brief interlude at UC Berkeley, CA, he became a group leader at the EMBL Heidelberg in 1988. Since 1997 he is a director at the Max Planck Institute of Biophysics in Frankfurt, Germany, where his department of Structural Biology studies the structure and mechanisms of membrane proteins by X-ray and electron crystallography, single-particle cryo-EM, electron tomography and biophysical techniques.

Professor Sir John Walker FRS studied chemistry at St Catherine’s College Oxford. After periods of study and research at the University of Wisconsin USA, and The Pasteur Institute in Paris, in 1974 he joined the Medical Research Council’s Laboratory of Molecular Biology in Cambridge, where he established the details of the modified genetic code of mitochondria, helped to discover overlapping genes in bacteriophages and discovered the two eponymous protein sequence motifs involved in binding nucleotides. They are the most widely dispersed motifs in the entire biological kingdom. Here, he also developed his interest in how energy in food is converted into the molecule ATP, the energy currency of life. In 1994, his work led to the realisation that in a complex molecular machine in our bodies, the energy released by the oxidation of dietary sugars and fats is coupled by a mechanical rotary mechanism to the chemical synthesis of ATP. This work led to the award of the Nobel Prize in Chemistry in 1997. In 1998, he was appointed Director of the MRC Dunn Human Nutrition Unit in Cambridge, which became the MRC Mitochondrial Biology Unit in 2008. Since 2013 he has been Director Emeritus. Here he continues to delve deeper into the fundamental basis of energy conversion in biology. He is a Fellow of the Royal Society, and in 2012, he received its Copley Medal, the UK’s highest scientific accolade. He is also a Fellow of the Academy of Medical Sciences, a Fellow of Sidney Sussex College, Cambridge, a Foreign Member of L’Accademia Nazionale dei Lincei, the Royal Netherlands Academy of Arts and Sciences, The Royal Society of New Zealand and a Foreign Associate of the US National Academy of Sciences.

Bill Cramer's career can be summarized as a step down by a factor of 10 to the exponent nineteen, the energy in electron-volts (eV) of the cosmic rays that he studied as an undergraduate and grad student, to the 1 eV characteristic energy of the electron transfer events that he studies in analysis of structure-function of the photosynthetic cytochrome b6f electron transport complex. As a consequence of attempts to follow these different trajectories of charged atomic particles, and studies on other problems in membrane protein structural biology, he is a Fellow of the Biophysical Society and Henry Koffler Distinguished Professor of Biological Sciences at Purdue University.

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 Biochem. Soc), Wheland Medal (Univ. 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 Distinguished Visitor to Singapore.  Much of his research has focused on PSII and the water splitting process that it catalyses and obtained its crystal structure in 2004. He is now investigating inorganic systems to mimic PSII in order develop technology for non-polluting solar fuels.

Jean-David Rochaix gained a Physics diploma in 1968 from the University of Lausanne, his PhD in Biophysics in 1972 from Harvard University.  From 1972-1974 he was a post-doctoral fellow (Fogarty NIH fellowship) in the Department of Biology, Yale University.  From 1974-1981 he was Chargé de recherches, Department of Molecular Biology, University of Geneva, and since 1981 he has been Professor, Departments of Molecular Biology and Plant Biology, University of Geneva.  His departments study the biogenesis of the photosynthetic apparatus of the green unicellular alga Chlamydomonas reinhardtii and the land plant Arabidopsis using mostly molecular-genetic approaches. This process involves a concerted interplay between two genetic systems localized in the chloroplast and nucleus of the cells and is strongly influenced by environmental conditions. They also study the acclimation of plants and algae to changes in the quality and quantity of light. In this way, they have identified and characterized some of the key players in this acclimation process which are the Stt7/STN7 and Stl1/STN8 thylakoid protein kinases and the PPH1/TAB38 protein phosphatase.

Peter Nixon is currently a Professor of Biochemistry within the Department of Life Sciences at Imperial College London and a visiting Professor within the School of Biological Sciences at Nanyang Technological University, Singapore. His research focuses on the assembly and maintenance of the photosynthetic apparatus in the thylakoid membrane and more recently the use of synthetic biology approaches to develop cyanobacterial and chloroplasts as ‘solar biorefineries’ for the production of high-value products. He is co-convenor of the Photosynthesis and Metabolism Group of the Society of Experimental Biology.

Jane Langdale is Professor of Plant Developmental Genetics, and Head of the Department of Plant Sciences, at the University of Oxford. Her research on chloroplast development started in the late 1980s when she worked on the genetic mechanisms underpinning dimorphic chloroplast development in the C₄ plant maize. That work led on to the identification of GLK transcription factors, that regulate chloroplast development in all land plant species studied so far. More recently she has been involved in the multi-national effort to engineer ‘C₄ rice’.
