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:0000256|ARBA:ARBA00003406}.
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:0000256|ARBA:ARBA00004808}.
CC -!- SIMILARITY: Belongs to the HdrB family.
CC {ECO:0000256|ARBA:ARBA00010431}.
