L-threonine 3-dehydrogenase
In enzymology, L-threonine 3-dehydrogenase is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are L-threonine and oxidised nicotinamide adenine dinucleotide. Its products are -2-amino-3-ketobutyric acid, reduced NADH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-threonine:NAD+ oxidoreductase. Other names in common use include L-threonine dehydrogenase, threonine 3-dehydrogenase, and threonine dehydrogenase. This enzyme participates in glycine, serine and threonine metabolism.
