Enzyme Commission Summary:
Catalyses the transfer of a methyl group from the N5 group of methyltetrahydrofolate to the 5-methoxybenzimidazolylcobamide cofactor of a corrinoid/Fe-S protein. Involved, together with EC 126.96.36.199, carbon-monoxide dehydrogenase (ferredoxin) and EC 188.8.131.52, CO-methylating acetyl-CoA synthase, in the reductive acetyl coenzyme A (Wood-Ljungdahl) pathway of autotrophic carbon fixation in various bacteria and archaea.
