The 3 substrates of this enzyme are CoA, NAD+, and NADP+, whereas its 4 products are CoA-disulfide, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is CoA:NAD(P)+ oxidoreductase. Other names in common use include CoA-disulfide reductase (NADH2), NADH2:CoA-disulfide oxidoreductase, CoA:NAD+ oxidoreductase, CoADR, and coenzyme A disulfide reductase.
