>cd01977 Nitrogenase_VFe_alpha Nitrogenase_VFe_alpha -like: Nitrogenase VFe protein, alpha subunit like. This group contains proteins similar to the alpha subunits of, the VFe protein of the vanadium-dependent (V-) nitrogenase and the FeFe protein of the iron only (Fe-) nitrogenase Nitrogenase catalyzes the ATP-dependent reduction of dinitrogen (N2) to ammonia. In addition to V- and Fe- nitrogenases there is a molybdenum (Mo)-dependent nitrogenase which is the most widespread and best characterized of these systems. These systems consist of component 1 (VFe protein, FeFe protein or, MoFe protein respectively) and, component 2 (Fe protein). MoFe is an alpha2beta2 tetramer, V-and Fe- nitrogenases are alpha2beta2delta2 hexamers. The alpha and beta subunits of VFe and FeFe are similar to the alpha and beta subunits of MoFe. For MoFe each alphabeta pair contains one P-cluster (at the alphabeta interface) and, one molecule of iron molybdenum cofactor (FeMoco) contained within the alpha sub
