1.8.7.3	2 oxidized ferredoxin [iron-sulfur] cluster + CoB + CoM = 2 reduced ferredoxin [iron-sulfur] cluster + CoM-S-S-CoB + 2 H+	reaction mechanism, overview	-, 764753	
1.8.7.3	2 oxidized ferredoxin [iron-sulfur] cluster + CoB + CoM = 2 reduced ferredoxin [iron-sulfur] cluster + CoM-S-S-CoB + 2 H+	subunit HdrB of heterodisulfide reductase (HdrABC-MvhAGD) contains two noncubane [4Fe-4S] clusters tht are involved in reduction activity. The heterodisulfide is clamped between the two noncubane [4Fe-4S] clusters and homolytically cleaved, forming coenzyme M and B bound to each iron. Coenzymes are consecutively released upon one-by-one electron transfer	-, 765831
