Abstract excerpt
Rhizobium meliloti FixL and FixJ are members of a symbiotically essential two-component system that regulates nitrogen-fixation genes in response to environmental oxygen concentrations. FixL is a membrane protein that is thought to relay information about oxygen availability to FixJ via a phosphotransfer mechanism. FixJ increases expression of the nifA and fixK genes by activating transcription of the nifA and...
