CC -!- FUNCTION: Catalyzes the reduction of Delta(1)-pyrroline-2-carboxylate
CC (Pyr2C) to L-proline, using NADPH as the electron donor. May be
CC involved in a degradation pathway that converts trans-3-hydroxy-L-
CC proline (t3LHyp) to L-proline. {ECO:0000269|PubMed:24980702}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-proline + NAD(+) = 1-pyrroline-2-carboxylate + H(+) + NADH;
CC Xref=Rhea:RHEA:20321, ChEBI:CHEBI:15378, ChEBI:CHEBI:39785,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:60039; EC=1.5.1.49;
CC Evidence={ECO:0000269|PubMed:24980702};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-proline + NADP(+) = 1-pyrroline-2-carboxylate + H(+) +
CC NADPH; Xref=Rhea:RHEA:20317, ChEBI:CHEBI:15378, ChEBI:CHEBI:39785,
CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:60039; EC=1.5.1.49;
CC Evidence={ECO:0000269|PubMed:24980702};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=4 mM for Delta(1)-pyrroline-2-carboxylate (using NADPH as
CC cosubstrate) {ECO:0000269|PubMed:24980702};
CC Note=kcat is 25 sec(-1) for Pyr2C reduction using NADPH.
CC {ECO:0000269|PubMed:24980702};
CC -!- SIMILARITY: Belongs to the ornithine cyclodeaminase/mu-crystallin
CC family. {ECO:0000305}.
