Function

ACSE_MOOTH Methyltransferase that mediates the transfer of a N5-methyl group of (6S)-methyltetrahydrofolate to the 5-methoxybenzimidazolylcobamide cofactor of a corrinoid/Fe-S protein in the anaerobic acetyl-CoA pathway (Wood-Ljungdahl pathway) of carbon monoxide and carbon dioxide fixation.^{[1] [2] [3]}
