Lysine nutritional requirements of broilers reared in clean and dirty environments during the pre-starter and starter phases

open access: yesRevista Brasileira de Zootecnia, 2011
A total of 3,760 Ross male broiler chicks were used in two trials, one in the pre-starter (1-11 days) phase and the other in the starter (12-22 days) phase.

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Amino acid uptake in Arabidopsis [PDF]

open access: yes, 2008
Nitrogen (N) is essential for all living organisms and is considered to be the limiting factor for plant growth in many ecosystems. Although generally believed to rely on mineral N to fulfill their N needs, plants have also been found to access organic N

Digestible lysine levels in semi-heavy laying hens in the period from 28 to 44 weeks of age

open access: yesActa Scientiarum: Animal Sciences, 2014
This study aimed to evaluate the performance of laying hens subjected to heavy semi-low crude protein (14.0%) and lysine levels while maintaining the same relation of digestible amino acid/ digestible lysine.

Utilization of ileal digestible amino acids by pigs: Lysine [PDF]

open access: yesBritish Journal of Nutrition, 1990
Two experiments were conducted to determine the utilization of ileal digestible lysine by pigs. In the first, the apparent ileal digestibility of amino acids in cottonseed meal, meat-and-bone meal and soya-bean meal was determined in pigs fitted with‘T'-shaped cannulas.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Amino acids and central fatigue

open access: yes, 2001
There is an increasing interest in the mechanisms behind central fatigue, particularly in relation to changes in brain monoamine metabolism and the influence of specific amino acids on fatigue.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Digestible Methionine + Cysteine-to-Lysine Ideal Ratio for Meat-Type Quails at Initial Phase

open access: yesBrazilian Journal of Poultry Science
This trial was performed to determine the ideal ratio of digestible methionine + cysteine (Met/Lys) with digestible lysine for meat-type quails from 1 to 14 days of age. A total of six hundred thirty, one-day-old, not sexed meat type quails were randomly

Diferentes critérios de formulação de rações para frangos de corte no período de 1 a 21 dias de idade Different criterion of feed formulation for broilers in the period 1 to 21 days of age

open access: yesBrazilian Journal of Poultry Science, 2002
Dois experimentos foram realizados com o objetivo de avaliar diferentes critérios de formulação de rações, baseados em aminoácidos totais e digestíveis, para frangos de corte no período de 1 a 21 dias de idade.
