Urea Nitrogen Metabolite Can Contribute to Implementing the Ideal Protein Concept in Monogastric Animals [PDF]

Animals, 2022
The ideal protein concept refers to dietary protein with an amino acid profile that exactly meets an animal’s requirement. Low-quality protein levels in the diet have negative implications for productive and reproductive traits, and a protein oversupply ...

Fragon: rapid high-resolution structure determination from ideal protein fragments. [PDF]

Acta Crystallogr D Struct Biol, 2018
Correctly positioning ideal protein fragments by molecular replacement presents an attractive method for obtaining preliminary phases when no template structure for molecular replacement is available. This has been exploited in several existing pipelines.

Biomarkers and De Novo Protein Design Can Improve Precise Amino Acid Nutrition in Broilers

Animals, 2022
Precision nutrition in broilers requires tools capable of identifying amino acid imbalances individually or in groups, as well as knowledge on how more digestible proteins can be designed for innovative feeding programs adjusted to animals’ dynamic ...

Qualidade da carne de peito de frangos de corte recebendo rações com diferentes relações lisina digestível: proteína bruta Breast muscle meat quality of broiler chickens fed diets with different digestible lysine: crude protein ratios

Revista Brasileira de Zootecnia, 2008
Avaliou-se o efeito de diferentes relações lisina digestível/proteína bruta (LD:PB) sobre as características químicas e físicas do músculo do peito de frangos de corte, machos, da linhagem Cobb, aos 42 dias de idade.

Mobility of the SecA 2-helix-finger is not essential for polypeptide translocation via the SecYEG complex [PDF]

, 2012
The bacterial ATPase SecA and protein channel complex SecYEG form the core of an essential protein translocation machinery. The nature of the conformational changes induced by each stage of the hydrolytic cycle of ATP and how they are coupled to protein ...

How Does Protein Nutrition Affect the Epigenetic Changes in Pig? A Review

Animals, 2021
Epigenetic changes regulate gene expression and depend of external factors, such as environment and nutrition. In pigs, several studies on protein nutrition have been performed to improve productive and reproductive traits.

Diets formulated on total or digestible amino acid basis with different energy levels and physical form on broiler performance

Brazilian Journal of Poultry Science, 2005
We studied the effects of two different systems of expressing amino acid requirements (total - TAA or digestible - DAA), two energy levels (2,900 or 3,200 kcal of ME/kg) and two physical forms (mash or pellet) on the performance of male broilers from 21 ...
