This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (R)-2-hydroxyacid:NAD(P)+ oxidoreductase. Other names in common use include (R)-sulfolactate:NAD(P)+ oxidoreductase, L-sulfolactate dehydrogenase, ComC, and (R)-sulfolactate dehydrogenase.
