Accepted name: 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase [NAD(P)H]
Reaction: (1) L-pipecolate + NAD(P)+ = 1-piperideine-2-carboxylate + NAD(P)H + H+
(2) L-proline + NAD(P)+ = 1-pyrroline-2-carboxylate + NAD(P)H + H+
Other name(s): Δ1-pyrroline-2-carboxylate reductase; DELTA1-pyrroline-2-carboxylate reductase; DELTA1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase (ambiguous); AbLhpI; pyrroline-2-carboxylate reductase; L-proline:NAD(P)+ 2-oxidoreductase
Systematic name: L-pipecolate/L-proline:NAD(P)+ 2-oxidoreductase
Comments: The enzymes, characterized from the bacterium Azospirillum brasilense, is involved in trans-3-hydroxy-L-proline metabolism. In contrast to EC, 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase (NADPH), which is specific for NADPH, this enzyme shows similar activity with NADPH and NADH.
