NifX-like domain (IPR034169)

Short name: NifX-like

Overlapping homologous superfamilies

Domain relationships


NifX belongs to a family of iron-molybdenum cluster-binding proteins that includes NifB, and NifY, all of which are involved in the synthesis of an iron-molybdenum cofactor (FeMo-co) that binds the active site of the dinitrogenase enzyme. The protein is part of the nitrogen fixation gene cluster in nitrogen-fixing bacteria and has sequence similarity to other members of the cluster [PMID: 2747620, PMID: 10217770]. This domain is also found C-terminal in NifY, which is also part of the nif cluster [PMID: 2644218].
