Scientists around the world have been striving to develop artificial light-harvesting antenna model systems for energy and other light-driven biochemical applications. Among the various approaches to achieve this goal, one of the most promising is the assembly of structurally well-defined artificial light-harvesting antennas based on the principles of structural DNA nanotechnology. DNA has recently emerged as an extremely efficient material to organize molecules such as fluorophores and proteins on the nanoscale. It is desirable to develop a hybrid smart material by combining artificial antenna systems based on DNA with natural reaction center components, so that the material can be engineered to convert light energy to chemical energy via formation of a charge-separated state. Presented here are a series of studies toward this goal. First, self-assembled seven-helix DNA bundles (7HB) with cyclic arrays of three distinct chromophores were developed. The spectral properties and energy transfer mechanisms in the artificial light-harvesting antenna were studied extensively using steady-state and time-resolved methods. Next, engineered cysteine residues in the reaction center of the purple photosynthetic bacterium Rhodobacter sphaeroides were each covalently conjugated to fluorophores in order to explore the spectral requirements for energy transfer between an artificial light harvesting system and the reaction center. Finally, a structurally well-defined and spectrally tunable artificial light-harvesting system was constructed, where multiple organic dyes were conjugated to 3-arm DNA nanostructure. A reaction center protein isolated from the purple photosynthetic bacterium Rhodobacter sphaeroides was linked to one end of the 3-arm junction to serve as the final acceptor, which converts the photonic energy absorbed by the chromophores into chemical energy by charge separation. This type of model system is required to understand how parameters such as geometry, spectral characteristics of the dyes, and conformational flexibility affect energy transfer, and can be used to inform the development of more complex model light-harvesting systems.

This landmark collective work introduces the physical, chemical, and biological principles underlying photosynthesis: light absorption, excitation energy transfer, and charge separation. It begins with an introduction to properties of various pigments, and the pigment proteins in plant, algae, and bacterial systems. It addresses the underlying physics of light harvesting and key spectroscopic methods, including data analysis. It discusses assembly of the natural system, its energy transfer properties, and regulatory mechanisms. It also addresses light-harvesting in artificial systems and the impact of photosynthesis on our environment. The chapter authors are amongst the field’s world recognized experts. Chapters are divided into five main parts, the first focused on pigments, their properties and biosynthesis, and the second section looking at photosynthetic proteins, including light harvesting in higher plants, algae, cyanobacteria, and green bacteria. The third part turns to energy transfer and electron transport, discussing modeling approaches, quantum aspects, photoinduced electron transfer, and redox potential modulation, followed by a section on experimental spectroscopy in light harvesting research. The concluding final section includes chapters on artificial photosynthesis, with topics such as use of cyanobacteria and algae for sustainable energy production.

Algae, including cyanobacteria, are in the spotlight today for a number of reasons; firstly it has become abundantly clear over recent years that algae have been neglected in terms of basic research and that knowledge gap is being rapidly closed with the establishment of some surprising discoveries, such as the presence of Near-Infra-Red-Absorbing cyanobacteria and a wealth of natural products; secondly molecular approaches have provided a wealth of approaches to genetically modify algae and produce value-added products; thirdly it has become clear just how important, marine phytoplankton is to global carbon capture and the production of food globally; and fourthly, it has also become clear that algae present unparalleled opportunities to generate biofuels in a sustainable and non-polluting way. This volume presents 15 chapters by world experts on their subjects, ranging from reviews of algal diversity and genetics to in-depth reviews of special algal groups such as diatoms (which account for over 30% of marine carbon capture). Other chapters chart the ways in which this carbon capture occurs or how there are a multiplicity of ways in which algae intercept sun light and deploy this energy for carbon capture. A fascinating aspect here is the way in which sun light is harvested. A special chapter is devoted to the very recent and exciting possibility that algae use coherent light energy transformation to enhance the efficiency of light capture, an aspect of quantum physics that has implications for future developments at several levels and a variety of industries. Just how and why algae use Chlorophyll a as the major light capture pigment is discussed in several chapters. However, attention is also given to those cyanobacteria, which have been found to use the special Near-Infra Red absorbing chlorophylls mentioned above. And attention is also given to those algae that employ phycobiliproteins to fill in the “green window”, i.e., the spectral region from 400 – 650 nm, which is not efficiently covered by chlorophyll and carotenoid pigments. Photoinhibition and photoprotection is the subject area of several chapters and one which it is essential to understand a we work towards greater efficiency of algal photosynthesis. A final chapter is devoted to understanding the molecular basis for coral bleaching, a much-neglected area that is essential in trying to come up with solutions to this very worrying phenomenon, caused by global warming and ocean acidification. This is a book for research scientists, environmentalists, planners in a range of areas including those of marine resources, nutrient control and pollution of water bodies and that growing body of concerned citizens interested in controlling carbon emissions and global warming. Special attention has been given to generating a set of articles that will be read by university students, informed laymen and all those whose wish to understand the rapid changes that have come about in our knowledge of algae over the past decade.

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. The Photosynthetic Membrane: Molecular Mechanisms of Light Harvesting will appeal to a wide audience of undergraduate and postgraduate students as well as researchers working in the fields of biochemistry, molecular biology, biophysics, plant science and bioengineering.
