Molecule diagrams generated from .mol files obtained from the KEGG ftp site.

Comments: Catalyzes the transfer of a methyl group from the N(5) group of methyltetrahydrofolate to the 5-methoxybenzimidazolylcobamide cofactor of a corrinoid/Fe-S protein. Involved, together with Ec 1.2.7.4 and Ec 2.3.1.169, in the reductive acetyl coenzyme A (Wood-Ljungdahl) pathway of autotrophic carbon fixation in various bacteria and archaea.
