Membrane association of Klebsiella pneumoniae NifL is affected by molecular oxygen and combined nitrogen.

Archives of microbiology - 1 Mar 2002

Klopprogge Kai, Grabbe Roman, Hoppert Michael, Schmitz Ruth A

Abstract excerpt

In the diazotroph Klebsiella pneumoniae, NifL and NifA regulate transcription of the nitrogen fixation genes in response to molecular oxygen and combined nitrogen. We recently showed that Fnr is the primary oxygen sensor. Fnr transduces the oxygen signal towards the negative regulator NifL by activating genes whose products reduce the FAD moiety of NifL under anoxic conditions. These Fnr-dependent gene products...
