| Short Name | MtrH |
| description | In archaea the enzyme tetrahydromethanopterin S-methyltransferase is composed of eight subunits, MtrA-H. The enzyme is a membrane- associated enzyme complex which catalyzes an energy-conserving, sodium-ion-translocating step in methanogenesis from hydrogen and carbon dioxide []. Subunit MtrH catalyzes the methylation reaction and was shown to exhibit methyltetrahydromethanopterin:cob(I)alamin methyltransferase activity [].CH3-H4MPT + cob(I)alamin -->H4MPT + CH3-cob(III)alamin (H4MPT = tetrahydromethanopterin) |
