Interaction between the fumarate reductase system of Escherichia coli and the nitrogen fixation genes of Klebsiella pneumoniae.
For phenotypic expression of nif+Kp genes in Escherichia coli K-12, the anaerobic electron transport system to fumarate must be functional. The role of the fumarate reduction system is to energize the membrane and thus provide the energy necessary for nitrogen fixation.
