Download or read book Molybdenum Cofactors and Their role in the Evolution of Metabolic Pathways written by Luana Presta and published by Springer. This book was released on 2015-05-07 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this brief, the authors explore and review the current knowledge regarding the role of molybdenum in the evolution of biological systems and their interaction with biogeochemical cycles. Special emphasis is placed on biological nitrogen fixation and the nitrogen element cycle. The origin and evolution of molybdenum cofactor biosynthetic pathways as well as the evolutionary significance of molybdenum containing enzymes appearance is analyzed. Original data regarding nitrogen fixation pathways and related enzymes molecular evolution processes is presented. The trace element molybdenum is essential for nearly all organisms and forms the catalytic center of a large variety of enzymes such as nitrogenase, nitrate reductases, sulphite oxidase and xanthine oxidoreductases.
