2.1.1.377 |
| Accepted name: |
[methyl-Co(III) glycine betaine-specific corrinoid protein]—coenzyme M methyltransferase |
| Reaction: |
a [methyl-Co(III) glycine betaine-specific corrinoid protein] + CoM = methyl-CoM + a [Co(I) glycine betaine-specific corrinoid protein] |
| Other name(s): |
mtaA (gene name) |
| Systematic name: |
methylated glycine betaine-specific corrinoid protein:CoM methyltransferase |
| Comments: |
The enzyme, which is involved in methanogenesis from glycine betaine, catalyses the transfer of a methyl group bound to the cobalt cofactor of glycine betaine-specific corrinoid protein to coenzyme M, forming the substrate for EC 2.8.4.1, coenzyme-B sulfoethylthiotransferase, which catalyses the final step in methanogenesis. The enzyme from the methanogenic archaeon Methanolobus vulcani B1d can also catalyse the activity of EC 2.1.1.246, [methyl-Co(III) methanol-specific corrinoid protein]—coenzyme M methyltransferase. |
