In enzymology a cob(II)alamin reductase (EC 1.16.1.4) is an enzyme that catalyzes the chemical reaction2 cob(I)alamin + NAD+ 2 cob(II)alamin + NADH + H+Thus the two substrates of this enzyme are cob(I)alamin and NAD+ whereas its 3 products are cob(II)alamin NADH and H+.This enzyme belongs to the family of oxidoreductases specifically those oxidizing metal ion with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is cob(I)alamin:NAD+ oxidoreductase.
