ENZYME entry: EC 2.1.1.90
Accepted Name |
Methanol--corrinoid protein Co-methyltransferase.
|
Alternative Name(s) |
Methanol--5-hydroxybenzimidazolylcobamide Co-methyltransferase. |
Reaction catalysed |
Methanol + a [Co(I) methanol-specific corrinoid protein] <=> a [methyl-Co(III) methanol-specific corrinoid protein] + H(2)O |
Comment(s) |
- The enzyme, which catalyzes the transfer of methyl groups from
methanol to a methanol-specific corrinoid protein (MtaC), is involved
in methanogenesis from methanol.
- Methylation of the corrinoid protein requires the central cobalt to
be in the Co(I) state.
- During methylation the cobalt is oxidized to the Co(III) state.
- Free cob(I)alamin can substitute for the corrinoid protein in vitro.
- Inactivated by oxygen and other oxidizing agents, and reactivated by
catalytic amounts of ATP and hydrogen.
