Anomalies in the refinement of isoleucine [PDF]

Acta Crystallographica Section D Biological Crystallography, 2014
A study of isoleucines in protein structures solved using X-ray crystallography revealed a series of systematic trends for the two side-chain torsion angles χ1and χ2dependent on the resolution, secondary structure and refinement software used. The average torsion angles for the nine rotamers were similar in high-resolution structures solved using ...

Elucidating the importance of the catabolic enzyme, methionine-gamma-lyase, in stresses during Arabidopsis seed development and germination

Frontiers in Plant Science, 2023
The sulfur-containing essential amino acid, methionine, is a key metabolite in plant cells since it is used as a precursor for the synthesis of vital metabolites.

Response of piglets to the standardized ileal digestible isoleucine, histidine and leucine supply in cereal–soybean meal-based diets

Animal, 2013
Improving the amino acid (AA) profile of the diet by using l-Lys, l-Thr, dl-Met, l-Trp and l-Val helps to reduce the dietary CP content, thereby reducing nitrogen excretion while maintaining the performance of pigs.

Plasmodium schizont densities in culture grown with and without isoleucine, as well as isoleucine starvation for different durations of time

, 2021
To test the effect of the amino acid isoleucine on the parasite asexual cycle we compared parasite developmental progression in cultures with and without isoleucine (50 mg/L), as well as after different durations (7, 14, 18 hours) of isoleucine ...

Effects of L-valine in layer diets containing 0.72% isoleucine. [PDF]

, 2022
In a previous study with LSL-LITE layers (-23 to 30-week-old), isoleucine at 0.72% and 0.84% produced values for FCR at 1.45 and 1.44, respectively and shared significance with 0.78% isoleucine (1.49). Considering that FCR is an important standard in the

Biosynthesis of food constituents: Amino acids: 1. The glutamic acid and aspartic acid groups - a review

Czech Journal of Food Sciences, 2006
This review article gives a survey of principal pathways that lead to the biosynthesis of the proteinogenic amino acids of the glutamic acid group (glutamic acid, glutamine, proline, arginine) and aspartic acid group (aspartic acid, asparagine, threonine,

Amino acid racemization dating: Method development using African ostrich (Struthio camelus) eggshell [PDF]

, 2013
Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis.

Research Note: The influence of different isoleucine: lysine ratios on the growth performance of broiler chickens fed low-protein diets

Poultry Science, 2023
Two trials were carried out to assess the effects of different ratios of standardized ileal digestible isoleucine:lysine (SID Ile:Lys) on the growth performance of broiler chickens fed low-protein diets. A total of 1,320 male chickens were distributed in

Relationship Between Serum Amino Acid Levels and Bone Mineral Density: A Mendelian Randomization Study

Frontiers in Endocrinology, 2021
BackgroundThis study aimed to explore the association between serum amino acids (AAs) levels and bone mineral density (BMD).MethodsWe performed a two-sample Mendelian randomization (MR) analysis to analyze the associations between the levels of eight AAs
