Pyrroline-2-carboxylate reductase

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 L-proline:NAD(P)+ 2-oxidoreductase. This enzyme is also called Delta1-pyrroline-2-carboxylate reductase. This enzyme participates in lysine degradation and arginine and proline metabolism.
