Few problems in protein biochemistry have proven to be as challenging and recalcitrant as the molecular description of nitrogenase, the catalyst of one of the most remarkable chemical transformations in biological systems: the nucleotide-dependent reduction of atmospheric dinitrogen to bioavailable ammonia.  In Nitrogen Fixation: Methods and Protocols, recognized experts in the field provide an up-to-date, in-depth overview of the methods that have been applied to studying the nitrogenase at a molecular level, ranging from genetic, biochemical, spectroscopic, and chemical methods to theoretical calculations. In addition, techniques used to study an enzyme system that is homologous to nitrogenase are described in ...
