Comments

FUNCTION: Part of a complex that catalyzes the reversible reduction of CoM-S-S-CoB to the thiol-coenzymes H-S-CoM (coenzyme M) and H-S-CoB (coenzyme B). HdrE may be responsible for anchoring the complex to the membrane.
CATALYTIC ACTIVITY: Coenzyme B + coenzyme M + methanophenazine = N-(7-((2-sulfoethyl)dithio)heptanoyl)-O³-phospho-L-threonine + dihydromethanophenazine.
PATHWAY: Cofactor metabolism; coenzyme B/coenzyme M regeneration; coenzyme B and coenzyme M from CoB-CoM heterodisulfide: step 1/1 .
SUBUNIT: The heterodisulfide reductase 2 is composed of two subunits; hdrD and hdrE (By similarity).
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein (Potential).
MISCELLANEOUS: Methanophenazine seems to mediate electron transfer from a F420-non-reducing hydrogenase to the heterodisulfide reductase 2.
SIMILARITY: Belongs to the hdrE family.
