Enzyme Information
| 2.1.1.248 |
[Methylamine--corrinoid protein] Co-methyltransferase.
based on mapping to UniProt O30642
Methylamine + a [Co(I) methylamine-specific corrinoid protein] = a [methyl-Co(III) methylamine-specific corrinoid protein] + ammonia.
-!- The enzyme, which catalyzes the transfer of a methyl group from methylamine to a methylamine-specific corrinoid protein (MtmC), is involved in methanogenesis from methylamine. -!- The enzyme contains the unusual amino acid pyrrolysine. -!- Methylation of the corrinoid protein requires the central cobalt to be in the Co(I) state. -!- During methylation the cobalt is oxidized to the Co(III) state. -!- The methylated corrinoid protein is substrate for EC 2.1.1.247.
