K22011 cfbA; sirohydrochlorin cobalto/nickelchelatase
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 2.8.4.1, coenzyme-B sulfoethylthiotransferase. It catalyses the insertion of the nickel ion into sirohydrochlorin.
