Part II examines the components and their function on the donor side. Part III discusses the biochemistry of the water oxidation enzyme system, polypeptide composition, and functional reconstitution. Part IV take up the functions of chloride and bicarbonate in electron transport and the mechanism of photoactivation in latent or Tris-inactivated chloroplasts. Part V discusses the fate of reducing equivalents going through the two-electron gate mechanism, together with the biochemistry of the quinone components on the acceptor side.
Book Synopsis Assembly of the Photosystem II Membrane-Protein Complex of Oxygenic Photosynthesis by : Julian J. Eaton-Rye
Download or read book Assembly of the Photosystem II Membrane-Protein Complex of Oxygenic Photosynthesis written by Julian J. Eaton-Rye and published by Frontiers Media SA. This book was released on 2017-08-08 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photosystem II is a 700-kDa membrane-protein super-complex responsible for the light-driven splitting of water in oxygenic photosynthesis. The photosystem is comprised of two 350-kDa complexes each made of 20 different polypeptides and over 80 co-factors. While there have been major advances in understanding the mature structure of this photosystem many key protein factors involved in the assembly of the complex do not appear in the holoenzyme. The mechanism for assembling this super-complex is a very active area of research with newly discovered assembly factors and subcomplexes requiring characterization. Additionally the ability to split water is inseparable from light-induced photodamage that arises from radicals and reactive O2 species generated by Photosystem II chemistry. Consequently, to sustain water splitting, a “self repair” cycle has evolved whereby damaged protein is removed and replaced so as to extend the working life of the complex. Understanding how the biogenesis and repair processes are coordinated is among several important questions that remain to be answered. Other questions include: how and when are the inorganic cofactors inserted during the assembly and repair processes and how are the subcomplexes protected from photodamage during assembly? Evidence has also been obtained for Photosystem II biogenesis centers in cyanobacteria but do these also exist in plants? Do the molecular mechanisms associated with Photosystem II assembly shed fresh light on the assembly of other major energy-transducing complexes such as Photosystem I or the cytochrome b6/f complex or indeed other respiratory complexes? The contributions to this Frontiers in Plant Science Research Topic are likely to reveal new details applicable to the assembly of a range of membrane-protein complexes, including aspects of self-assembly and solar energy conversion that may be applied to artificial photosynthetic systems. In addition, a deeper understanding of Photosystem II assembly — particularly in response to changing environmental conditions — will provide new knowledge underpinning photosynthetic yields which may contribute to improved food production and long-term food security.

Download or read book Photosystem II written by T. Wydrzynski and published by Springer Science & Business Media. This book was released on 2006-01-27 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most mysterious part of photosynthesis yet the most important for all aerobic life on Earth (including ourselves) is how green plants, algae and cyanobacteria make atmospheric oxygen from water. This thermodynamically difficult process is only achieved in Nature by the unique pigment/protein complex known as Photosystem II, using sunlight to power the reaction. The present volume contains 34 comprehensive chapters authored by 75 scientific experts from around the world. It gives an up-to-date account on all what is currently known about the molecular biology, biochemistry, biophysics and physiology of Photosystem II. The book is divided into several parts detailing the protein constituents, functional sites, tertiary structure, molecular dynamics, and mechanisms of homeostasis. The book ends with a comparison of Photosystem II with other related enzymes and bio-mimetic systems. Since the unique water-splitting chemistry catalyzed by Photosystem II leads to the production of pure oxygen gas and has the potential for making hydrogen gas, a primary goal of this book is to provide a molecular guide to future protein engineers and bio-mimetic chemists in the development of biocatalysts for the generation of clean, renewable energy from sunlight and water.

Book Synopsis Photosynthesis in the Marine Environment by : Sven Beer
Download or read book Photosynthesis in the Marine Environment written by Sven Beer and published by John Wiley & Sons. This book was released on 2014-05-27 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Marine photosynthesis provides for at least half of the primary production worldwide..." Photosynthesis in the Marine Environment constitutes a comprehensive explanation of photosynthetic processes as related to the special environment in which marine plants live. The first part of the book introduces the different photosynthesising organisms of the various marine habitats: the phytoplankton (both cyanobacteria and eukaryotes) in open waters, and macroalgae, marine angiosperms and photosymbiont-containing invertebrates in those benthic environments where there is enough light for photosynthesis to support growth, and describes how these organisms evolved. The special properties of seawater for sustaining primary production are then considered, and the two main differences between terrestrial and marine environments in supporting photosynthesis and plant growth are examined, namely irradiance and inorganic carbon. The second part of the book outlines the general mechanisms of photosynthesis, and then points towards the differences in light-capturing and carbon acquisition between terrestrial and marine plants. This is followed by discussing the need for a CO2 concentrating mechanism in most of the latter, and a description of how such mechanisms function in different marine plants. Part three deals with the various ways in which photosynthesis can be measured for marine plants, with an emphasis on novel in situ measurements, including discussions of the extent to which such measurements can serve as a proxy for plant growth and productivity. The final chapters of the book are devoted to ecological aspects of marine plant photosynthesis and growth, including predictions for the future.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein dynamics play a key role in enzyme-catalyzed reactions. Vibrational spectroscopy provides a method to follow these structural changes and thereby describe the reaction coordinate as a function of space and time. A vibrational spectroscopic technique, reaction-induced FTIR spectroscopy, has been applied to the study of the oxygen-evolving complex (OEC) of photosystem II (PSII). In plant photosynthesis, PSII evolves oxygen from the substrate, water, by the accumulation of photo-oxidizing equivalents at the OEC. Molecular oxygen and protons are the products of this reaction, which is responsible for the maintenance of an aerobic atmosphere on earth. The OEC is a Mn4CaO5 cluster with nearby bound chloride ions. Sequentially oxidized states of the OEC are termed the S states. The dark-stable state is S1, and oxygen is released on the transition from S3 to S0. Using short laser flashes, individual S states are generated, allowing vibrational spectroscopy to be used to study these different oxidation states of the OEC. In current X-ray crystal structures, hydrogen bonds to water molecules are predicted to form an extensive network around the Mn4CaO5 cluster. In the OEC, four peptide carbonyl groups are linked to the water network, which extends to two Mn-bound and two Ca-bound water molecules. This dissertation discusses a vibrational spectroscopic method that uses these peptide carbonyl frequencies as reporters of solvatochromic changes in the OEC. This technique provides a new, high-resolution method with which to study water and protein dynamics in PSII and other enzymes.
