Enzyme Commission Primary Name: 5-methyltetrahydrofolate:corrinoid/iron-sulfur protein Co-methyltransferase

Enzyme Commission Synonyms: acsE (gene name)

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, carbon-monoxide dehydrogenase (ferredoxin) and EC, CO-methylating acetyl-CoA synthase, in the reductive acetyl coenzyme A (Wood-Ljungdahl) pathway of autotrophic carbon fixation in various bacteria and archaea.
