1.5.1.1 |
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 1.5.1.21, 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase (NADPH), which is specific for NADPH, this enzyme shows similar activity with NADPH and NADH. |

Systematic name: |
L-pipecolate/L-proline:NADP+ 2-oxidoreductase |
Comments: |
The enzyme is involved in the catabolism of D-lysine and D-proline in bacteria that belong to the Pseudomonas genus. In contrast to EC 1.5.1.1, 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase [NAD(P)H], which shows similar activity with NADPH and NADH, this enzyme is specific for NADPH. |

Accepted name: |
1-pyrroline-2-carboxylate reductase [NAD(P)H] |
Reaction: |
L-proline + NAD(P)+ = 1-pyrroline-2-carboxylate + NAD(P)H + H+ |
Systematic name: |
L-proline:NAD(P)+ 2-oxidoreductase |
Comments: |
The enzyme from the bacterium Colwellia psychrerythraea is involved in trans-3-hydroxy-L-proline metabolism. In contrast to EC 1.5.1.1, 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase [NAD(P)H], which shows similar activity with 1-piperideine-2-carboxylate and 1-pyrroline-2-carboxylate, this enzyme is specific for the latter. While the enzyme is active with both NADH and NADPH, activity is higher with NADPH. |
