Computer quantum chemical modeling of the interaction of calcium phosphate with amino acids

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022
In this work, a quantum-chemical modeling of the process of interaction of calcium phosphate with amino acids was carried out. Within the framework of the quantum chemical modeling, the total energy of the molecular complex E, the energy difference ...

TFIIIR Is an Isoleucine tRNA [PDF]

Molecular and Cellular Biology, 1994
Promoter-specific transcription by silkworm RNA polymerase III is dependent on several transcription factors (TFs) in addition to the polymerase itself. The activities present in silk gland nuclear extracts that are necessary to reconstitute transcription from class III genes in vitro have been resolved into several partially purified components. These

Amino acid content and biomass productivity of selected weed species as an indicator of their response to herbicide stress

Acta Agrobotanica, 2013
Biomass reduction and amino acid content in plants of Papaver rhoeas L. and Stellaria media L. were investigated to evaluate response of these species to herbicide stress under various temperature (25/16 and 8/2 oC) and relative humidity (50 and 75 ...

Self-assembly of Alanine-Isoleucine and Isoleucine-Isoleucine Dipeptides through Atomistic Simulations and Experiments

The Journal of Physical Chemistry B, 2020
A detailed investigation of the structural and conformational properties of alanine-isoleucine (Ala-Ile) and isoleucine-isoleucine (Ile-Ile) dipeptides is presented in water and in methanol solvents. We propose a consistent combination of complementary simulation and experimental methods, covering a broad range of length and time scales, from the very ...

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.

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 ...

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,
