ENZYME entry: EC 1.8.7.3
Accepted Name |
ferredoxin:CoB-CoM heterodisulfide reductase.
|
Reaction catalysed |
coenzyme B + coenzyme M + 2 oxidized [2Fe-2S]-[ferredoxin] <=> coenzyme M-coenzyme B heterodisulfide + 2 H(+) + 2 reduced [2Fe-2S]-[ferredoxin] |
Comment(s) |
- HdrABC is an enzyme complex that is found in most methanogens and
catalyzes the reduction of the CoB-CoM heterodisulfide back to CoB
and CoM.
- HdrA contains a FAD cofactor that acts as the entry point for
electrons, which are transferred via HdrC to the HdrB catalytic
subunit.
- One form of the enzyme from Methanosarcina acetivorans (HdrA2B2C2)
can also catalyze EC 1.8.98.4. cf. EC 1.8.98.5, EC 1.8.98.6,
and EC 1.8.98.1.
