1.8.98.5 | coenzyme B-coenzyme M disulfide + ferredoxin + 2 H2 | HdrABC catalyzes the CoM-S-S-CoB-dependent reduction of ferredoxin with H2, coupling the endergonic reduction of ferredoxin to the exergonic reduction of coenzyme B-coenzyme M disulfide. Per mole CoM-S-S-CoB added, 1 mol of ferredoxin is reduced, indicating an electron bifurcation coupling mechanism. The stoichiometry of coupling is consistent with an ATP gain per mole methane from 4 H2 and CO2 of near 0.5 | Methanothermobacter marburgensis | coenzyme B + coenzyme M + reduced ferredoxin2- + 2 H+ | - |
