Nucleotide sequence of nifD from Frankia alni strain ArI3: phylogenetic inferences

Abstract : The complete nucleotide sequence of the nifD gene encoding the alpha subunit of component I of nitrogenase from Frankia alni strain ArI3 was determined. The coding region is 1,458 bp in length and encodes a polypeptide of 486 residues with a predicted molecular weight of 53,500. Phylogenetic inferences with 12 complete published nifD sequences were drawn using a variety of approaches. Frankia nifD clusters with proteobacteria rather than with Clostridium pasteurianum, the other Gram-positive bacterium studied. Extant eubacterial nif genes seem to have at least three distinct evolutionary origins as a result of ancient gene duplications. Within the Gram-positive bacterial phylum, functional nif genes descend from different duplicates.
