Entry
EC 1.8.98.1                 Enzyme                                 

Name
dihydromethanophenazine:CoB-CoM heterodisulfide reductase;
hdrDE (gene names);
CoB---CoM heterodisulfide reductase (ambiguous);
heterodisulfide reductase (ambiguous);
coenzyme B:coenzyme M:methanophenazine oxidoreductase
Class
Oxidoreductases;
Acting on a sulfur group of donors;
With other, known, physiological acceptors
Sysname
CoB:CoM:methanophenazine oxidoreductase
Reaction(IUBMB)
CoB + CoM + methanophenazine = CoM-S-S-CoB + dihydromethanophenazine [RN:R04540]
Reaction(KEGG)
R04540
Substrate
CoB [CPD:C04628];
CoM [CPD:C03576];
methanophenazine [CPD:C11903]
Product
CoM-S-S-CoB [CPD:C04832];
dihydromethanophenazine [CPD:C11904]
Comment
This enzyme, found in methanogenic archaea that belong to the Methanosarcinales order, regenerates CoM and CoB after the action of EC 2.8.4.1, coenzyme-B sulfoethylthiotransferase. It is a membrane-bound enzyme that contains (per heterodimeric unit) two distinct b-type hemes and two [4Fe-4S] clusters. cf. EC 1.8.7.3, ferredoxin:CoB-CoM heterodisulfide reductase, EC 1.8.98.5, H2:CoB-CoM heterodisulfide,ferredoxin reductase, EC 1.8.98.6, formate:CoB-CoM heterodisulfide,ferredoxin reductase and EC 1.8.98.4, coenzyme F420:CoB-CoM heterodisulfide,ferredoxin reductase.
