(S)-carnitine 3-dehydrogenase

In enzymology, a (S)-carnitine 3-dehydrogenase is an enzyme that catalyzes the chemical reaction


 * (S)-carnitine + NAD$+$ $$\rightleftharpoons$$ 3-dehydrocarnitine + NADH + H$+$

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.
