Vanadium/alternative nitrogenase delta subunit (IPR004349)

Short name: V/Nase_d_su

Overlapping homologous superfamilies


Family relationships


The nitrogenase complex EC: catalyses the conversion of molecular nitrogen to ammonia (nitrogen fixation). The complex is hexameric, consisting of 2 alpha, 2 beta, and 2 delta subunits.

This family represents the delta subunit of a group of nitrogenases that do not utilise molybdenum (Mo) as a cofactor, but instead use either vanadium (V nitrogenases), or iron (alternative nitrogenases).
