ENTRY       EC 2.1.1.90
NAME        Methanol--5-hydroxybenzimidazolylcobamide Co-methyltransferase
CLASS       Transferases
            Transferring one-carbon groups
            Methyltransferases
SYSNAME     Methanol:5-hydroxybenzimidazolylcobamide Co-methyltransferase
REACTION    Methanol + 5-Hydroxybenzimidazolylcobamide =
            Co-Methyl-Co-5-hydroxybenzimidazolylcob(I)amide + H2O
SUBSTRATE   Methanol
            5-Hydroxybenzimidazolylcobamide
PRODUCT     Co-Methyl-Co-5-hydroxybenzimidazolylcob(I)amide
            H2O
COMMENT     The enzyme form Methanosarcina barkeri contains 3-4 molecules of
            bound 5-hydroxybenzimidazolylcobamide which act as methyl
            acceptor.  Inactivated by oxygen and other oxidizing agents, and
            reactivated by catalytic amounts of ATP and hydrogen.
