IUBMB Enzyme Nomenclature


Accepted name: [methyl-Co(III) methoxylated-aromatic-compound-specific corrinoid protein]—tetrahydrofolate methyltransferase

Reaction: [a methyl-Co(III) methoxylated-aromatic-compound-specific corrinoid protein] + tetrahydrofolate = N5-methyltetrahydrofolate + a [Co(I) methoxylated-aromatic-compound-specific corrinoid protein]

Other name(s): mtvA (gene name)

Systematic name: [methylated methoxylated-aromatic-compound-specific corrinoid protein]:tetrahydrofolaten methyltransferase

Comments: The enzyme, found in acetogenic bacteria, participates in a pathway for the degradation of methoxylated aromatic compounds (methoxydotrophic growth). The enzyme catalyses the transfer of a methyl group bound to the cobalt cofactor of a dedicated corrinoid protein (MtvC) to tetrahydrofolate. cf. EC, [methyl-Co(III) methoxylated-aromatic-compound-specific corrinoid protein]—tetrahydromethanopterin methyltransferase.
