Accepted name: Ni-sirohydrochlorin a,c-diamide reductive cyclase
Reaction: ATP + Ni-sirohydrochlorin a,c-diamide + 3 reduced electron acceptor + H2O = ADP + phosphate + 15,173-seco-F430-173-acid + 3 electron acceptor
Other name(s): cfbC (gene name); cfbD (gene name)
Systematic name: Ni-sirohydrochlorin a,c-diamide reductive cyclo-ligase (ADP-forming)
Comments: The enzyme, studied from the methanogenic archaeon Methanosarcina acetivorans, participates in the biosynthesis of the nickel-containing tetrapyrrole cofactor coenzyme F430, which is required by EC, coenzyme-B sulfoethylthiotransferase.
