CC -!- FUNCTION: Part of a complex that catalyzes the reversible reduction of
CC CoM-S-S-CoB to the thiol-coenzymes H-S-CoM (coenzyme M) and H-S-CoB
CC (coenzyme B). {ECO:0000250|UniProtKB:Q6LY39}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00711};
CC Note=Binds 2 [4Fe-4S] clusters per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00711};
CC -!- PATHWAY: Cofactor metabolism; coenzyme M-coenzyme B heterodisulfide
CC reduction; coenzyme B and coenzyme M from coenzyme M-coenzyme B
CC heterodisulfide: step 1/1. {ECO:0000250|UniProtKB:Q6LY39}.
CC -!- SUBUNIT: The heterodisulfide reductase is composed of three subunits;
CC HdrA, HdrB and HdrC. {ECO:0000250|UniProtKB:Q6LY39}.
CC -!- SIMILARITY: Belongs to the HdrC family. {ECO:0000305}.
