Proline metabolism and NAD kinase activity in greenbean plants subjected to cold-shock.
The aim of the present work was to examine the relationship between proline metabolism and NAD kinase activity in greenbeans submitted to cold-shock. For this, 15-day-old greenbean plants were subjected to a temperature of 4 degrees C (cold shock) for 180 min. Our results indicate that the plants showed foliar accumulation of proline, with the enzymes ornithine-delta-aminotransferase (OAT) and ...
متن کاملProline metabolism and microenvironmental stress.
Proline, the only proteinogenic secondary amino acid, is metabolized by its own family of enzymes responding to metabolic stress and participating in metabolic signaling. Collagen in extracellular matrix, connective tissue, and bone is an abundant reservoir for proline. Matrix metalloproteinases degrading collagen are activated during stress to make proline available, and proline oxidase, the f...
متن کاملSalt stress-induced changes in leaf antioxidant activity, proline and protein content in ‘Shah Anjir’ and ‘Anjir Sabz’ fig seedlings
A major portion of the Iranian fig (Ficus carica) industry is located in high-salinity regions, and salinity is an important limiting factor in the production of this fruit. The present study was conducted to investigate the changes of leaf antioxidant-enzyme activity, proline and total protein content in two fig cultivars with two leaf shapes: ‘Anjir Sabz’ with lobate and palmate leaves, and ‘...
متن کاملSubstrate channeling in proline metabolism.
Proline metabolism is an important pathway that has relevance in several cellular functions such as redox balance, apoptosis, and cell survival. Results from different groups have indicated that substrate channeling of proline metabolic intermediates may be a critical mechanism. One intermediate is pyrroline-5-carboxylate (P5C), which upon hydrolysis opens to glutamic semialdehyde (GSA). Recent...
متن کاملMiRNA and Proline Metabolism in Cancer
Tumor metabolism and bioenergetics are important areas for cancer research and present promising targets for anticancer therapy. Growing tumors alter their metabolic profiles to meet the bioenergetic and biosynthetic demands of increased cell growth and proliferation. These alterations include the well-known aerobic glycolysis, the Warburg effect, which has been considered as the central tenet ...
