Cross-functionality of nitrogenase components NifH1 and VnfH in Anabaena variabilis.

Journal of bacteriology - 1 Aug 2006

Abstract excerpt

Anabaena variabilis fixes nitrogen under aerobic growth conditions in differentiated cells called heterocysts using either a Mo nitrogenase or a V nitrogenase. The nifH1 gene, which encodes the dinitrogenase reductase of the Mo nitrogenase that is expressed only in heterocysts, is cotranscribed with nifD1 and nifK1, which together encode the Mo dinitrogenase. These genes were expressed in the presence or absence...
