>TIGR01287 nifH nitrogenase iron protein; InterPro: IPR005977 The enzyme responsible for nitrogen fixation, the nitrogenase, shows a high degree of conservation of structure, function, and amino acid sequence across wide phylogenetic ranges. All known Mo-nitrogenases consist of two components, component I (also called dinitrogenase, or Fe-Mo protein), an alpha2beta2 tetramer encoded by the nifD and nifK genes, and component II (dinitrogenase reductase, or Fe protein) a homodimer encoded by the nifH gene , . Two operons, nifDK and nifEN, encode a tetrameric (alpha2beta2 and N2E2) enzymatic complex. Nitrogenase contains two unusual rare metal clusters; one of them is the iron molybdenum cofactor (FeMo-co), which is considered to be the site of dinitrogen reduction and whose biosynthesis requires the products of nifNE and of some other nif genes . It has been proposed that NifNE might serve as a scaffold upon which FeMo-co is built and then inserted into component I .; GO: 0016163 nitrogenase activity, 0009399 nitrogen fixation, 0016612 molybdenum-iron nitrogenase complex.
