Requirement of nifV gene for production of wild-type nitrogenase enzyme in Klebsiella pneumoniae


Klebsiella pneumoniae nitrogenase is a complex enzyme consisting of two component proteins, the tetrameric MoFe protein (Kp1) and the dimeric Fe protein (Kp2)1. Together these catalyse the ATP-dependent reduction of N2 and of several triple-bonded substrates such as C2H2, CN−, N−3 and CH3NC (refs 2, 3). In the absence of substrate, protons are reduced to H2… (More)
