Disease relevance of nifD1

The genes encoding the structural components of nitrogenase, nifH, nifD and nifK, from the fast-growing, broad-host-range Rhizobium strain ANU240 have been identified and characterized [1].
The DNA sequence was determined for the Azospirillum brasilense nifH gene and part of the nifD gene [2].

High impact information on nifD1

We present the entire DNA sequence of the nifD and nifK genes, thus completing the characterisation of the primary structure of the nitrogenase genes in this Rhizobium strain [3].
Strain CE3 has three copies; nifHa and nifHb form part of nifHDK operons with the nitrogenase structural genes, while nifHc is linked to a truncated nifD homolog [4].
Genetic diversity among the strains was studied using RAPD markers and PCR-RFLP of 16S rDNA and nifD genes [5].

Other interactions of nifD1

The genes encoding the Molybdenum-Iron protein component of nitrogenase (nifD and nifK) have been identified and fully characterised in the Parasponia Rhizobium strain ANU289 [3].
