Book Description
In Heme, Chlorophyll, and Bilins: Methods and Protocols, an interdisciplinary panel of hands-on investigators describe in detail how to work successfully with chlorophyll, heme, and bilins in biological, medical, chemical, and biochemical research. Each method is presented by a researcher who actually uses it on a daily basis and includes step-by-step instructions and pertinent tricks-of-the-trade that often make the difference between laboratory success and failure. Topics range from methods for the analysis of tetrapyrroles,heme, and hemoproteins, to the biosynthesis and analysis of chlorophyll and bilins.

Book Description
The Porphyrin Handbook, Volume 13: Chlorophylls and Bilins: Biosynthesis, Synthesis, and Degradation provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into eight chapters, this volume begins with an overview of magnesium chelatase as a complex enzyme involved in the biosynthesis of chlorophyll and bacteriochlorophyll. This text then provides an accurate historical review of the two enzymes involved in photosynthetic pigment production. Other chapters consider the processes that take place in darkness in all plants including angiosperms as the early steps of chlorophyll biosynthesis. This book discusses as well the reactivity and structures of the known chlorophyll catabolites from vascular plants, synthetic sources, and microorganisms. The final chapter deals with the methodologies used for the synthesis of bile pigments. This book is a valuable resource for research scientists, engineers, and clinicians.

Book Description
Heme and chlorophyll (Chl) are porphyrins. Porphyrins (also referred to as tetrapyrroles) are essential for life in the biosphere. Chlorophyll catalyzes the conversion of solar energy to chemical energy via the process of photosynthesis. Organic life in the biosphere is made possible by consumption of the chemical energy generated by photosynthesis. Hemes are the prosthetic groups of cytochromes which are involved in electron transport during oxidative phosphorylation and photosynthetic phosphorylation which generate ATP and NADPH. The latter are essential for many cellular functions. Chlorophyll on the other hands catalyzes the process of photosynthesis. Indeed, life in the biosphere depends on the process of photosynthesis which converts light energy, carbon dioxide and water into the chemical energy, required for the formation of food and fiber. Photosynthetic efficiency is controlled by extrinsic factors such as the availability of water, CO2, inorganic nutrients, ambient temperature and the metabolic and developmental state of the plant, as well as by intrinsic factors (Lien and San Pietro, 1975). The most important intrinsic factor is the efficiency of the photosynthetic electron transport system (PETS). Conventional agriculture is one of the few human activities that have not undergone a revolution to join other activities such as overcoming gravity by flying, and landing on the moon, crossing underwater the polar cap, and communicating wirelessly over long distances via electromagnetic waves. We now feel that enough biochemical and molecular biological knowledge has accumulated to render this dream amenable to experimentation. We believe that the time has come to bioengineer chloroplasts capable of synthesizing a short chain carbohydrate such as glycerol at rates that approach the upper theoretical limits of photosynthesis [Rebeiz, C. A. (2010) Investigations of possible relationships between the chlorophyll biosynthetic pathway and the assembly of chlorophyll-protein complexes and photosynthetic efficiency. In: Rebeiz, C. A. Benning, C., Bohnert, H.J., Daniell, H., Hoober J. K., Lichtenthaler, H. K., Portis , A. R., and Tripathy, B. C. eds. The chloroplast: Basics and Applications. Springer. The Netherlands, p 1-24]. In order to achieve this goal a thorough knowledge of the Chl biosynthetic pathway is needed along with knowledge in other domains (Rebeiz 2010). In this context, this monograph is devoted to an in depth discussion of our present knowledge of the Chl biosynthetic pathway. The complexity and biochemical heterogeneity of the Chl biosynthetic pathway and the relationship of this complexity to the structural and biosynthetic complexity of photosynthetic membranes will be emphasized. We will also emphasize in historical perspective, key stages in our understanding of the Chl biosynthetic heterogeneity. The reader should keep in mind that a complex biosynthetic process is only fully understood when it becomes possible to reconstitute in vitro every step of the process. We are not yet at this stage of understanding of thylakoid membrane biogenesis. Considerable progress has been achieved however, in the understanding of numerous facets of the Chl biosynthetic pathway, namely (a) detection and identification of various major and minor metabolic intermediates (b) precursor-product relationships between various intermediates, (c) structure and regulation of many enzymes of the pathway, and (d) the relationship of the Chl biosynthetic heterogeneity to the structural and functional heterogeneity of thylakoid membranes. In addition topics related to the development of Analytical techniques, Cell-free systems, Herbicides, Insecticides, and Cancericides are also discussed.

Book Description
Excluding the biological polymers proteins, lipids and nucleic acids, modified tetrapyrroles are the biological molecules that have had the greatest impact on the evolution of life over the past 4 billion years. They are involved in a wide variety of fundamental processes that underpin central primary metabolism in all kingdoms of life, from photosynthesis to methanogenesis. Moreover, they bring colour into the world and it is for this reason that these compounds have been appropriately dubbed the ‘pigments of life’. To understand how and why these molecules have been so universally integrated into the life processes one has to appreciate the chemical properties of the tetrapyrrole scaffold and, where appropriate, the chemical characteristics of the centrally chelated metal ion. This book addresses why these molecules are employed in Nature, how they are made and what happens to them after they have finished their usefulness.

Book Description
Originally published as the stand-alone Chlamydomonas Sourcebook, then expanded as the second volume in a three-part comprehensive gold-standard reference, The Chlamydomonas Sourcebook: Organellar and Metabolic Processes has been fully revised and updated to include a wealth of new knowledge and resources for the Chlamydomonas community. It details the tremendous progress recently made with respect to imaging the ultrastructure of cells, dissecting acclimation and biosynthetic responses, and elucidating molecular processes underlying the biology of organelles. In particular, this volume includes exciting new developments in the use of imaging technologies for examining supramolecular organization of the chloroplast, defining mechanisms of branched electron transfer pathways in photosynthesis, dissecting the organization of pyrenoids and CO2 concentration mechanisms, presenting the intricacies associated with acclimation to environmental conditions and providing new insights into dark metabolism and the network of fermentative metabolism. This book thus presents the latest advances in both the research and uses of new experimental approaches and technologies, making this a must-have resource for researchers and students working in plant science and photosynthesis, fertility, mammalian vision, aspects of human disease, acclimation to environmental change, and the biogenesis of cellular complexes. - Describes molecular techniques, analysis of the recently sequenced genome, reviews of the current status of the diverse fields in which Chlamydomonas is used as a model organism - Provides methods for Chlamydomonas research and best practices for their applications; this includes methods for cell culture, preservation of cultures, preparation of media, lists of inhibitors, and other additives to culture media, classical genetic manipulation, and new approaches for gene transfer and editing technologies - Assists researchers with common laboratory problems such as contamination
