>TIGR01283 nifE nitrogenase MoFe cofactor biosynthesis protein NifE; InterPro: IPR005973 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: 0005515 protein binding, 0006461 protein complex assembly, 0009399 nitrogen fixation.
