Substrate 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 کاملInborn errors of proline metabolism.
l-Proline concentration is primarily related to the balance of enzymatic activities of proline dehydrogenase [proline oxidase (POX)] and Delta-1-pyrroline-5-carboxylate (P5C) reductase. As a result, P5C plays a pivotal role in maintaining the concentration of proline in body fluids and inborn errors of P5C metabolism lead to disturbance of proline metabolism. Several inborn errors of proline me...
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 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 ...
متن کاملTHE EFFECT OF SALINITY STRESS ON PROLINE METABOLISM IN TWO WHEAT (TRITICUM AESTIVUM) CULTIVARS
The effect of various NaCl treatments (0, 50, 100, 200 and 300 mM) at different growth and development stages (tillering, boot swelling, flowering and polination) of two wheat cultivars (Ghods : salt-sensitive; Boolani : salt-resistant) on proline concentration and the kinetic activity of proline dehydrogenase was studied under greenhouse conditions. Generally, in response to salinity treatment...
