Lysine caused a greater depression in growth of chicks fed a diet con taining casein than a diet containing a combination of safflower meal, corn gluten meal and soybean meal. Clycine, in the presence of arginine, appeared to exhibit a synergistic effect in alleviating the growth depression induced by an excess of lysine. Similarly, glycine supplementation decreased nitrogen retention in a diet...

Highly selective binding of basic amino acids, i.e. lysine, arginine, and histidine, by a negatively charged carboxylatopillar[5]arene (CP5A) is reported. And the complexation behavior of the CP5A host towards lysine metabolites including cadaverine (Cad), acetyl-l-lysine (AcLys) and trimethyl-l-lysine (TMLys) is also described.

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...

BACKGROUND Lysine affects diarrhea and anxiety via effects on serotonin receptors, enhanced intestinal repair, and sodium chloride-dependent opioid peptide transport. OBJECTIVE The objective was to investigate the effects of lysine supplementation on morbidity, growth, and anxiety in children and adults of peri-urban areas of Accra, Ghana. DESIGN In a double-blind randomized trial, the effe...

In planning the present experiment it was assumed that, if the diet of a lactating ruminant is devoid of lysine and the animal is in positive nitrogen balance, the lysine in the milk must have been synthesized in the animal by the micro-organisms in its paunch. Lysine synthesis by rumen bacteria has been demonstrated by McDonald (1944) and by McNaught (1951). The former fed sheep on a diet in w...

The transcription of genes located in subtelomeric regions of yeast chromosomes is repressed relative to the rest of the genome. This repression requires wild-type nucleosome levels but not the telomere silencing factors Sir2, Sir3, Sir4, and Rap1. Subtelomeric heterochromatin is characterized by the absence of acetylation or methylation of histone H3 lysine residues, but it is not known whethe...

Hydroxylysine was first isolated from gelatin (2) and probably does not occur in proteins of mammalian origin other than collagen (3). In rats, dietary lysine is an obligatory precursor of the hydroxylysine of collagen (4-7); when 14C-labeled lysine is either fed or given by injection it is incorporated into both the lysine and hydroxylysine of collagen, whereas labeled hydroxylysine is not inc...

The poultry market has changed due to a higher consumer interest on products with differentiated organoleptic characteristics, making of free-range broiler production a promising activity. This experiment was conducted to determine the digestible lysine requirements of Redbro Cou Nu male and female chickens during the starter phase (one to 21 days of age). Six hundred and thirty Redbro Cou Nu b...
