General annotation (Comments)

Function	Housekeeping enzyme that catalyzes the last step in proline biosynthesis. Can utilize both NAD and NADP, but has higher affinity for NAD. Involved in the cellular response to oxidative stress By similarity.
Catalytic activity	L-proline + NAD(P)+ = 1-pyrroline-5-carboxylate + NAD(P)H.
Pathway	Amino-acid biosynthesis; L-proline biosynthesis; L-proline from L-glutamate 5-semialdehyde: step 1/1.
Subunit structure	Homodecamer; composed of 5 homodimers By similarity.
Subcellular location	Mitochondrion By similarity.
Sequence similarities	Belongs to the pyrroline-5-carboxylate reductase family.
