Oxidases and Related Redox Systems is a collection of papers from the Third International Symposium on Oxidases and Related Reduction Systems held in Albany, New York on July 3-7, 1979. This book deals with the oxygen and peroxide activating enzymes field. The book addresses electron transfer related to oxygen biochemistry by comparing quantum, semiclassical, and classical methods of electron transfer reactions. Several papers then discuss the active and toxic states of oxygen and superoxide as the discovery of superoxide dismutase activity of erythrocuprein can provide a means to studying oxygen reaction in biological systems. One paper then compares the active sites of molluskan and arthropodan hemocyanins, which are known as reversible oxygen-carriers. The result of this study is presented in a table. Other papers discuss the flavin catalyzed reactions of molecular oxygen and the implications of the physiological function of D-amino acid oxidase from inhibition studies. The book then explains the role of carbon monoxide in the reaction mechanism of oxygen with cytochrome oxidase. This collection will prove beneficial for research students and professors in the field of biochemistry and chemical physics.
