  • Title: Complete nucleotide sequence of the Azotobacter vinelandii nitrogenase structural gene cluster.
    Author: Brigle KE, Newton WE, Dean DR.
    Journal: Gene; 1985; 37(1-3):37-44. PubMed ID: 3863780.
    Abstract:
    DNA fragments coding for the structural genes for Azotobacter vinelandii nitrogenase have been isolated and sequenced. These genes, nifH, nifD and nifK, code for the iron (Fe) protein and the alpha and beta subunits of the molybdenum-iron (MoFe) protein, respectively. They are arranged in the order: promoter:nifH:nifD:nifK. There are 129 nucleotides separating nifH and nifD and 101 nucleotides separating nifD and nifK. The amino acid (aa) sequences deduced from the nucleotide sequences are discussed in relation to the prosthetic group-binding regions of the nifHDK-encoded polypeptides.
