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 220.127.116.11, Δ1-piperideine-2-carboxylate reductase, 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+] (18.104.22.168):
i1: L-pipecolate + NAD+ = 1-piperideine-2-carboxylate + NADH + 2 H+ (22.214.171.124)
