ID   2.1.1.252
DE   tetramethylammonium--corrinoid protein Co-methyltransferase.
AN   tetramethylammonium methyltransferase.
CA   Co(I)-[tetramethylammonium-specific corrinoid protein] + H(+) +
CA   tetramethylammonium = methyl-Co(III)-[tetramethylammonium-specific
CA   corrinoid protein] + trimethylamine.
CC   -!- The enzyme, which catalyzes the transfer of a methyl group from
CC       tetramethylammonium to a tetramethylammonium-specific corrinoid
CC       protein (MtqC), is involved in methanogenesis from
CC       tetramethylammonium.
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   -!- The methylated corrinoid protein is substrate for EC 2.1.1.253.
