ID 2.1.1.250 DE [trimethylamine--corrinoid protein] Co-methyltransferase. AN trimethylamine methyltransferase. CA Co(I)-[trimethylamine-specific corrinoid protein] + H(+) + trimethylamine CA = dimethylamine + methyl-Co(III)-[trimethylamine-specific corrinoid CA protein]. CC -!- The enzyme, which catalyzes the transfer of a methyl group from CC trimethylamine to a trimethylamine-specific corrinoid protein (MttC), CC is involved in methanogenesis from trimethylamine. CC -!- The enzyme contains the unusual amino acid pyrrolysine. 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 2.1.1.247.
