ID 2.1.1.90 DE methanol--corrinoid protein Co-methyltransferase. AN methanol--5-hydroxybenzimidazolylcobamide Co-methyltransferase. CA Co(I)-[methanol-specific corrinoid protein] + H(+) + methanol = H2O + CA methyl-Co(III)-[methanol-specific corrinoid protein]. CC -!- The enzyme, which catalyzes the transfer of methyl groups from CC methanol to a methanol-specific corrinoid protein (MtaC), is involved CC in methanogenesis from methanol. CC -!- Methylation of the corrinoid protein requires the central cobalt to CC be in the Co(I) state. CC -!- During methylation the cobalt is oxidized to the Co(III) state. CC -!- Free cob(I)alamin can substitute for the corrinoid protein in vitro. CC -!- Inactivated by oxygen and other oxidizing agents, and reactivated by CC catalytic amounts of ATP and hydrogen.
