... NifA in A. vinelandii . One interpretation of this result is that the uridylylation status of GlnK mediates the nitrogen regulation of nitrogen fixation through direct interaction with the NifL–NifA system. This is also suggested by the properties of a mutant form of GlnK, namely GlnK–Y51F, which...

... the intracellular nitrogen regulation (Ntr) system to external changes in ammonium availability. Given the almost invariant coupling of AmtB and GlnK in bacteria and archaea it seems probable that these two proteins may constitute an ancestral nitrogen-responsive system that has been coupled with a variety...
