Proline metabolism-related gene expression in four potato genotypes in response to drought stress
Biologia Plantarum, 2019 Drought severely limits potato yield. The aim of this work was to study a response of plantlets of four potato genotypes to polyethylene glycol (PEG 6000)-induced drought stress in both physiological and molecular levels. The drought-tolerant and drought-

The regulatory mechanisms of proline and hydroxyproline metabolism: Recent advances in perspective
Frontiers in Oncology, 2023 For diverse human tumors, growth and metastasis are dependent on proline synthesis, but the mechanisms underlying this association are not clear. Proline incorporated into collagen is primarily synthesized from glutamine.

A Nuclear Gene Encoding Mitochondrial Proline Dehydrogenase, an Enzyme Involved in Proline Metabolism, Is Upregulated by Proline but Downregulated by Dehydration in Arabidopsis [PDF]
The Plant Cell, 1996 Proline is one of the most common compatible osmolytes in water-stressed plants. The accumulation of proline in dehydrated plants is caused both by the activation of proline biosynthesis and by the inactivation of proline degradation; a decrease in the level of accumulated proline in rehydrated plants is caused both by the inhibition of proline ...

The effect of folic acid treatment on the post-harvest life of cucumber through influencing the activity of enzymes involved in the biosynthesis of proline, polyamine, and chlorophyll-degradation [PDF]
فیزیولوژی محیطی گیاهی, 2022 In this study, the mechanism of cold stress tolerance in cucumber fruits pretreated with folic acid was investigated. Control group and the group treated with 5 mgL-1 folic acid were stored for 15 days at 4 °-C.

Evidence for Hysteretic Substrate Channeling in the Proline Dehydrogenase and Δ1-Pyrroline-5-carboxylate Dehydrogenase Coupled Reaction of Proline Utilization A (PutA) [PDF]
Journal of Biological Chemistry, 2014 PutA (proline utilization A) is a large bifunctional flavoenzyme with proline dehydrogenase (PRODH) and Δ(1)-pyrroline-5-carboxylate dehydrogenase (P5CDH) domains that catalyze the oxidation of l-proline to l-glutamate in two successive reactions. In the PRODH active site, proline undergoes a two-electron oxidation to Δ(1)-pyrroline-5-carboxlylate, and

Toxicity of Free Proline Revealed in an Arabidopsis T-DNA-Tagged Mutant Deficient in Proline Dehydrogenase [PDF]
Plant and Cell Physiology, 2003 The toxicity of proline (Pro) to plant growth has raised questions despite its protective functions in response to environmental stresses. To evaluate Pro toxicity, we isolated an Arabidopsis T-DNA-tagged mutant, pdh, that had a defect in Pro dehydrogenase (AtProDH), which catalyzes the first step of Pro catabolism.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
