Mutant of<i>Azotobacter vinelandii</i>That Hyperproduces Nitrogenase Component II

Abstract

A mutant strain of Azotobacter vinelandii that is unable to fix N(2) produces high levels of nitrogenase component II. Activities of revertants from this mutant strain indicate that a single genetic lesion is responsible for both hyperproduction of component II and the inability to produce component I.
