The proteins that gather light for plant photosynthesis are embedded within cell membranes in a site called the thylakoid membrane (or the "photosynthetic membrane"). These proteins form the light harvesting antenna that feeds with energy a number of vital photosynthetic processes such as water oxidation and oxygen evolution, the pumping of protons across the thylakoid membranes coupled with the electron transport chain of the photosystems and cytochrome b6f complex, and ATP synthesis by ATP synthase utilizing the generated proton gradient.

The Photosynthetic Membrane: Molecular Mechanisms and Biophysics of Light Harvesting is an introduction to the fundamental design and function of the light harvesting photosynthetic membrane, one of the most common and most important structures of life. It describes the underlying structure of the membrane, the variety and roles of the membrane proteins, the atomic structures of light harvesting complexes and their macromolecular assemblies, the molecular mechanisms and dynamics of light harvesting and primary energy transformations, and the broad range of adaptations to different light environments. The book shows, using the example of the photosynthetic membrane, how complex biological structures utilize principles of chemistry and physics in order to carry out biological functions.

Professor Alexander V. Ruban, School of Biological and Chemical Sciences, Queen Mary University of London, UK. Professor Ruban is a Professor in Biophysics at Queen Mary University of London and holds a 'Professeur des Universites (Biochimie et biologie moleculaire)' title awarded by the French Ministry of Education. He obtained his PhD at the Institute of Plant Physiology at the Academy of Sciences of the Ukraine. His research has been instrumental in the discovery of the molecular basis of photoprotection in LHCII and the in vivo configuration and dynamics of higher plant xanthophylls in the thylakoid membrane. The Ruban Lab at Queen Mary is engaged in mechanistic photosynthesis research with a multidisciplinary approach applies molecular spectroscopy, biophysics and biochemistry to important problems in plant physiology, specifically, the role of the various components (proteins, lipids, pigments) and macrostructure in the functions and adaptive mechanisms of the photosynthetic membrane related to light harvesting and photoprotection in plants and algae. In addition, professor Ruban is interested in the universal properties of carotenoids in biological membranes, the molecular dynamics of these molecules in the modulation of membrane protein conformation and their functions.
