In enzymology a valine dehydrogenase (NADP+) (EC 1.4.1.8) is an enzyme that catalyzes the chemical reactionL-valine + H2O + NADP+ 3-methyl-2-oxobutanoate + NH3 + NADPH + H+The 3 substrates of this enzyme are L-valine H2O and NADP+ whereas its 4 products are 3-methyl-2-oxobutanoate NH3 NADPH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on the CH-NH2 group of donors with NAD+ or NADP+ as acceptor.
