The expression of nifA in Azorhizobium caulinodans requires a gene product homologous to Escherichia coli HF-I, an RNA-binding protein involved in the replication of phage Q beta RNA.
We report the characterization of a mutant of Azorhizobium caulinodans, isolated after ethyl methanesulfonate mutagenesis. This Nod+ Nif- Fix- mutant is unable to synthesize 10 of 15 polypeptides normally induced under conditions of nitrogen fixation. By using lacZ fusions it was shown that nifA and...
