Proline dehydrogenase

Proline dehydrogenase

In enzymology, a proline dehydrogenase is an enzyme that catalyzes the chemical reaction

L-proline + acceptor rightleftharpoons (S)-1-pyrroline-5-carboxylate + reduced acceptor

Thus, the two substrates of this enzyme are L-proline and acceptor, whereas its two products are (S)-1-pyrroline-5-carboxylate and reduced acceptor.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with other acceptors. The systematic name of this enzyme class is L-proline:acceptor oxidoreductase. Other names in common use include L-proline dehydrogenase, and L-proline:(acceptor) oxidoreductase. This enzyme participates in arginine and proline metabolism. It employs one cofactor, FAD.
