In the most prevalent pathway of proline synthesis, glutamate is phosphorylated to γ-glutamyl phosphate by γ-glutamyl kinase, reduced to γ-glutamyl semialdehyde by γ-glutamyl phosphate reductase, cyclized spontaneously to Δ(1)-pyrroline-5-carboxylate and reduced to proline by Δ(1)-pyrroline-5-carboxylate reductase.

Pyrroline-5-carboxylate synthetase (P5CS) and pyrroline-5-carboxylate reductase (P5CR) play a central role in grasses (Lolium perenne, Poa pratensis), and arginase (ARG), ornithine aminotransferase (OAT) and P5CR play a central role in legumes (Medicago lupulina, Lotus corniculatus).

They are caused by biallelic mutations in PYCR1 or ALDH18A1, encoding pyrroline-5-carboxylate reductase 1 and pyrroline-5-carboxylate synthase (P5CS), respectively, which both operate in the mitochondrial proline cycle.
Fischer et al., Frederick, United States. In Curr Opin Clin Nutr Metab Care, 2015
Of special interest, modulatory proteins such as parkinson protein 7 and oral cancer overexpressed 1 interact with pyrroline-5-carboxylate reductase, a critical component of the proline regulatory axis.

The two pathways for proline biosynthesis in higher plants share the last step, the conversion of δ(1)-pyrroline-5-carboxylate (P5C) to L-proline, which is catalyzed by P5C reductase (P5CR, EC 22.214.171.124) with the use of NAD(P)H as a coenzyme.
The peptide mass fingerprinting technique demonstrated that ORAOV1 bound to pyrroline-5-carboxylate reductase (PYCR), which is associated with proline metabolism and reactive oxygen species (ROS) production.
Overexpression of IbMas up-regulated the salt stress responsive genes, including pyrroline-5-carboxylate synthase, pyrroline-5-carboxylate reductase, SOD, psbA and phosphoribulokinase genes, under salt stress.

Microarray analyses showed that the changes in expression of several myeloid differentiation-related genes (GATA2, azurocidin 1, pyrroline-5-carboxylate reductase 1, matrix metallopeptidase -8, S100 calcium-binding protein A12, neutrophil cytosolic factor 2 and oncostatin M) induced by ATRA were disturbed in NB4MTOE cells.
The characteristic abnormality in the overall pattern of enzymes, in the concentrations of individual ones, and in the quality of pyrroline-5-carboxylate reductase was clearly evident in both primary and metastatic tumors.
The effects of sodium chloride (NaCl) and abscisic acid (ABA) on protein synthesis, protein hydrolysis, glutamine synthetase, Δ-pyrroline-5-carboxylate reductase and amino acid composition have been studied in aerial parts of Pennisetum typhoides (Stapf et Hubbard) seedlings.
