This book summarises current knowledge of the structure, function,biosynthesis and regulation of energy-transducing enzymes inmitochondria, chloroplasts and bacteria. Each of the twenty chapters is written by top experts in their field, and Prof. Ernster has ensured that the book as a whole gives a well-integrated picture of the present state of knowledge of the field at its different levels and complexities. Since the publication of Bioenergetics edited by Lars Ernster in 1984, (New Comprehensive Biochemistry Vol. 9) the whole field of bioenergetics has undergone a tremendous expansion. Additionally a transition from membrane bioenergetics to molecular bioenergetics has accompanied this expansion - due mainly to the spectacular progress in the field of molecular biology over the past twenty years.Hence this volume, Molecular Mechanisms in Bioenergetics , is certain to be of interest, not only to the specialist in bioenergetics, but also to researchers working in the various fields of biophysics, biochemistry, molecular biology, genetics, cell biology and physiology. Also of interest, this volume contains an historical introduction, including a list of earlier publications relating to the history of bioenergetics.
