Enzyme Commission Primary Name: 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase [NAD(P)H]
Enzyme Commission Synonyms: δ1-pyrroline-2-carboxylate reductase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -24.103516 [Latendresse13]
Enzyme Commission Summary:
The enzymes, characterized from from the bacterium Azospirillum brasilense, is involved in trans-3-hydroxy-L-proline metabolism. In contrast to EC 126.96.36.199, 1-piperideine-2-carboxylate/1-pyrroline-2-carboxylate reductase (NADPH), which is specific for NADPH, this enzyme shows similar activity with NADPH and NADH.
Instance reaction of [L-pipecolate + NAD(P)+ ← 1-piperideine-2-carboxylate + NAD(P)H + 2 H+] (188.8.131.52):
i1: L-pipecolate + NAD+ = 1-piperideine-2-carboxylate + NADH + 2 H+ (184.108.40.206)
