Accepted name: sirohydrochlorin nickelchelatase
Reaction: Ni-sirohydrochlorin + 2 H+ = sirohydrochlorin + Ni2+
Other name(s): cfbA (gene name)
Systematic name: Ni-sirohydrochlorin nickel-lyase (sirohydrochlorin-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. It catalyses the insertion of the nickel ion into sirohydrochlorin.
