In enzymology a protein-disulfide reductase (EC 1.8.1.8) is an enzyme that catalyzes the chemical reactionprotein dithiol + NAD(P)+ protein disulfide + NAD(P)H + H+The 3 substrates of this enzyme are protein dithiol NAD+ and NADP+ whereas its 4 products are protein 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.
