Mechanism of Mo-Dependent Nitrogenase

Abstract

Nitrogenase is the enzyme responsible for biological reduction of dinitrogen (N2) to ammonia, a form usable for life. Playing a central role in the global biogeochemical nitrogen cycle, this enzyme has been the focus of intensive research for over 60 years. This chapter provides an overview of the features of nitrogenase as a background to the subsequent chapters of this volume that detail the many methods that have been applied in an attempt to gain a deeper understanding of this complex enzyme.
