This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with other, known, acceptors. The systematic name of this enzyme class is coenzyme B:coenzyme M:methanophenazine oxidoreductase. Other names in common use include heterodisulfide reductase, and soluble heterodisulfide reductase. This enzyme participates in folate biosynthesis.
