In enzymology a L-threonine 3-dehydrogenase (EC 1.1.1.103) is an enzyme that catalyzes the chemical reactionL-threonine + NAD+ L-2-amino-3-oxobutanoate + NADH + H+Thus the two substrates of this enzyme are L-threonine and NAD+ whereas its 3 products are L-2-amino-3-oxobutanoate NADH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
