Accession | GenProp0288 | |
Name | tetrahydromethanopterin S-methyltransferase complex | |
Type | SYSTEM | |
Description | This complex of eight subunits, MtrA-H, effects the transfer of a methyl froup from tetrahydromethanopterin to coenzyme M using a cobalamin (B12) cofactor residing on MtrA. This transfer is coupled to an energy-driven sodium-ion pump. Methane is subsequently released by a two-electron reduction of the methyl-coenzyme M by the enzyme methyl-coenzyme M reductase. | |
