Class of enzymes

(Methyl-Co(III) methanol-specific corrinoid protein):coenzyme M methyltransferase (EC 2.1.1.246, methyltransferase 2, mtaA (gene)) is an enzyme with systematic name methylated methanol-specific corrinoid protein:coenzyme M methyltransferase.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

[methyl-Co(III) methanol-specific corrinoid protein] + coenzyme M ⇌ methyl-CoM + [Co(I) methanol-specific corrinoid protein]
Quick Facts Identifiers, EC no. ...

Free methylcob(I)alamin can substitute for the corrinoid protein in vitro.
