(S)-carnitine 3-dehydrogenase

In enzymology, a (S)-carnitine 3-dehydrogenase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are (S)-carnitine and NAD, whereas its 3 products are 3-dehydrocarnitine, 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. The systematic name of this enzyme class is (S)-carnitine:NAD oxidoreductase.
