a pH-dependent conformational change is required for methyl transfer in the forward and reverse directions, but this step is not rate-limiting, the pH-dependent protein conformational change in the ternary complex is linked to deprotonation of the active complexes

-
the methyltetrahydrofolate:corrinoid/iron-sulfur protein methyltransferase catalyzes transfer of the N5-methyl group from (6S)-methyltetrahydrofolate, i.e. CH3-H4folate, to the cobalt center of a corrinoid/iron-sulfur protein, CFeSP, forming methylcob(III)-amide and H4folate
