The Physiology and Genetics of Nitrogen Fixation
The enzymological studies of nitrogenase outlined in the previous chapter have led to important reassessments of nitrogen fixation in the biosphere, and have permitted rapid advances in the study of the genetics of nitrogen fixation. These developments have stemmed partly from the practical value of the acetylene test and partly from the recognition of the metalloenzyme character of nitrogenase, its extreme oxygen sensitivity and its apparent waste of ATP. In this chapter, certain physiological, ecological and genetical consequences of recent biochemical knowledge will be discussed.
