Methanol—5-hydroxybenzimidazolylcobamide Co-methyltransferase

Template:No footnotes Template:Infobox enzyme In enzymology, a methanol-5-hydroxybenzimidazolylcobamide Co-methyltransferase (Template:EC number) is an enzyme that catalyzes the chemical reaction

methanol + 5-hydroxybenzimidazolylcobamide $\rightleftharpoons$ Co-methyl-Co-5-hydroxybenzimidazolylcob(I)amide + H₂O

Thus, the two substrates of this enzyme are methanol and 5-hydroxybenzimidazolylcobamide, whereas its two products are Co-methyl-Co-5-hydroxybenzimidazolylcob(I)amide and H₂O.

This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is methanol:5-hydroxybenzimidazolylcobamide Co-methyltransferase. Other names in common use include methanol cobalamin methyltransferase, methanol:5-hydroxybenzimidazolylcobamide methyltransferase, and MT 1.
