MtsA acts both to demethylate dimethylsulfide and to methylate CoM using non-protein-bound cobalamin as an intermediate methyl carrier, dependence of the rate of the MtsA-catalyzed methylcobalamin:CoM methyl transfer reaction on methylcobalamin, overview. The subunit carries out both CoM methylation and DMS demethylation and can account for both corrinoid-dependent methyltransferase activities of the methylthiol:CoM methyltransferase. A model for the native methylthiol:coenzyme M methyltransferase in which MtsA mediates the methylation of corrinoid bound to MtsB with dimethylsulfide and subsequently demethylates MtsB-bound corrinoid with coenzyme M, overview |
