The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Direct generic reaction:
(S)-1-pyrroline-5-carboxylate + NAD(P)+ + 2 H2O = L-glutamate + NAD(P)H + H+ (no EC#)

Sub-reactions:
(S)-1-pyrroline-5-carboxylate + H+ + H2O ↔ L-glutamate-5-semialdehyde ,
L-glutamate-5-semialdehyde + NAD+ + H2O → L-glutamate + NADH + 2 H+

Standard Gibbs Free Energy (ΔrG in kcal/mol): 7.055786 Inferred by computational analysis [Latendresse13]
