Proline metabolism as regulatory hub
Trends in Plant Science, 2022Proline is a multifunctional amino acid that is accumulated in high concentrations in plants under various stress conditions. Proline accumulation is intimately connected to many cellular processes, such as osmotic pressure, energy status, nutrient availability, changes in redox balance, and defenses against pathogens.

Proline metabolism in cartilage: The importance of proline biosynthesis
Metabolism, 1978Abstract Mammalian cells have the capacity to synthesize proline from ornithine or glutamic acid, although preformed proline usually is available from extracellular sources. We have measured the rate of proline formation from ornithine in the presence of physiologic concentrations of proline. In rat xiphoid cartilage organ cultures with ornithine and

Amino Acids, 1997
Sepsis is characterized by an abnormal increase in plasma proline (PRO) level, which tends to be related to the severity of disease. This study has been performed to assess the relationship between changes in plasma PRO and levels and doses of other amino acids (AA) in critically ill septic patients undergoing total parenteral nutrition (TPN).

Proline metabolism in Trypanosoma scelopori epimastigotes
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974Abstract 1. 1. Oxygen uptake by epimastigotes of Trypanosoma scelopori was stimulated by l -proline and to a lesser degree by l -aspartate. 2. 2. l -Proline reversed partially KCN-induced inhibition of respiration and, completely, inhibition caused by malonate. 3. 3.

Proline metabolism in Leishmania tarentolae
Experimental Parasitology, 1969Abstract Leptomonads of Leishmania tarentolae were able to grow in Trager's defined medium C deficient in glucose or l -proline, but not without both. In addition, inositol and glycine could be deleted without any adverse effect as long as either glucose or l -proline was present.

Proline metabolism in Trypanosoma cruzi epimastigotes
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976Abstract 1. 1. Oxygen uptake by epimastigotes of Trypanosoma cruzi , Costa Rica strain, was stimulated by l -proline, l -glutamate and to a lesser degree by l -aspartate. 2. 2. l -proline reversed partially malonate-induced inhibition of respiration but did not reverse KCN-induced inhibition. 3. 3.

Effect of Dietary Proline on Proline Metabolism in the Neonatal Pig
The Journal of Nutrition, 1989The effect of two dietary concentrations of proline (10.3 and 15.8 g/kg) on proline-metabolizing enzymes [pyrroline-5-carboxylate (P5C) reductase and proline oxidase], plasma and tissue free proline concentrations and growth were investigated in the 2- to 13-d-old pig. Diet had no effect on growth or enzyme activity. Diet had a significant (P less than

Besides their function as building blocks for proteins, certain amino acids have other important physiological roles. Such is the case of the non-polar imino acid proline and of lysine, a basic amino acid. Proline is accumulated by bacterial cells during osmotic stress as one of the prevalent compatible solutes that act as osmoprotectants21, 39.

Proline Metabolism in Leishmania donovani Promastigotes*
The Journal of Protozoology, 1972SYNOPSISOxygen uptake of Leishmania donovani culture promastigotes was stimulated by L‐proline and to a lesser extent by L‐glutamate and L‐arginine. L‐proline reversed partially KCN‐induced inhibition of respiration and completely, inhibition caused by malonate.
