Effect of dietary lysine on hepatic lysine catabolism in broilers.
Lysine is frequently a first- or second-limiting amino acid in poultry diets. Improving the efficiency of lysine use for protein synthesis would effectively lower the lysine requirement and decrease feed costs. Understanding how lysine is degraded and how the degradation is regulated would identify potential molecular targets for interventions to decrease lysine degradation. To better understan...
متن کاملLysine metabolism is concurrently regulated by synthesis and catabolism in both reproductive and vegetative tissues.
The functional role of Lys catabolism in balancing Lys levels in plants has only been directly demonstrated in developing seeds. Seed-specific expression of a bacterial feedback-insensitive dihydrodipicolinate synthase (DHPS) in an Arabidopsis knockout mutant of the AtLKR/SDH gene that regulates Lys catabolism synergistically boosted Lys accumulation in mature seeds, but it also severely reduce...
متن کاملRegulation of lysine catabolism in higher plants.
Lysine is an essential amino acid for mammals but its concentration in cereals, one of our main food sources, is low. Research over the past 40 years has unraveled many biochemical and molecular details of the aspartic acid pathway, which is the main route of lysine biosynthesis in plants. However, genetic manipulation of this pathway has not been successful at producing high-lysine seeds. This...
متن کاملLysine Catabolism in Barley (Hordeum vulgare L.).
Lysine catabolism in seedlings of barley (Hordeum vulgare L. var. Emir) was studied by direct injection of the following tracers into the endosperm of the seedlings: aspartic acid-3-(14)C, 2-aminoadipic acid-1-(14)C, saccharopine-(14)C, 2,6-diaminopimelic acid-1-(7)-(14)C, and lysine-1-(14)C. Labeled saccharopine was formed only after the administration of either labeled 2,6-diaminopimelic acid...
متن کاملCatabolism of L-lysine by Pseudomonas aeruginosa.
Pseudomonas aeruginosa PACI grows poorly on L-lysine as sole source of carbon but mutant derivatives which grow rapidly were readily isolated. Studies with one such mutant, P. aeruginosa PAC586, supported the existence of a route for L-lysine catabolism which differes from those reported previously in other species of Pseudomonas. The postulated route, the cadaverine or decarboxylase pathway, i...
