This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (S)-1-pyrroline-5-carboxylate:NAD+ oxidoreductase. Other names in common use include delta-1-pyrroline-5-carboxylate dehydrogenase, 1-pyrroline dehydrogenase, pyrroline-5-carboxylate dehydrogenase, pyrroline-5-carboxylic acid dehydrogenase, L-pyrroline-5-carboxylate-NAD+ oxidoreductase, and 1-pyrroline-5-carboxylate:NAD+ oxidoreductase. This enzyme participates in glutamate metabolism and arginine and proline metabolism.
