Abstract
Nitrogen fixation (nif) genes of diazotrophic enteric bacteria,Enterobacter cloacae orKlebsiella pneumoniae, are regulated bynif LA operon, in which thenif A product, NifA positively regulatesnif gene transcription, whereas the nifL product NifL represses it under oxygen or in excess of fixed nitrogen. Two-hybrid system was used to detect the possible interaction between NifA and NifL. The preliminary results illustrate that NifL does interact with NifA. The interaction between NifL and NtrC has also been shown.
