|Coenzyme F420:CoB-CoM heterodisulfide,ferredoxin reductase.
|2 oxidized coenzyme F420 + 2 reduced ferredoxin [iron-sulfur] cluster + CoB + CoM + 2 H(+) <=> 2 reduced coenzyme F420 + 2 oxidized ferredoxin [iron-sulfur] cluster + CoM-S-S-CoB|
- The enzyme, characterized from the archaeon Methanosarcina
acetivorans, catalyzes the reduction of CoB-CoM heterodisulfide back
to CoB and CoM.
- The enzyme consists of three components, HdrA, HdrB and HdrC, all of
which contain [4Fe-4S] clusters.
- Electrons enter at HdrA, which also contains FAD, and are transferred
via HdrC to the catalytic component, HdrB.
- During methanogenesis from acetate the enzyme catalyzes the activity
of EC 188.8.131.52.
- However, it can also use electron bifurcation to direct electron
pairs from reduced coenzyme F420 toward the reduction of both
ferredoxin and CoB-CoM heterodisulfide.
- This activity is proposed to take place during Fe(III)-dependent
anaerobic methane oxidation.
- Cf. EC 184.108.40.206, EC 220.127.116.11, and EC 18.104.22.168.
