TheRhizobium meliloti fdxN gene, which is part of thenifA-nifB fdxN operon, is absolutely required for symbiotic nitrogen fixation. The deduced sequence of the FdxN protein is characterized by two cysteine motifs typical of bacterial-type ferredoxins. The Fix− phenotype of anR. meliloti fdxN: :[Tc] mutant could be rescued by theR. leguminosarum fdxN gene, whereas no complementation was observed withnif-associated genes encoding ferredoxins fromBradyrhizobium japonicum, Azotobacter vinelandii, A… CONTINUE READING
