Synthetic and Crystalline Amino Acids: Alternatives to Soybean Meal in Chicken-Meat Production

Animals, 2020
Simple Summary There is a distinct possibility that synthetic and crystalline, or non-bound, amino acids will partially replace soybean meal in diets for broiler chickens and reduce the dependency of the chicken-meat industry on soybean meal as its ...

Chemically Fuelled Deracemization of Amino Acids [PDF]

, 2022
openSystems that work out-of-equilibrium are common in nature, living organisms are the most striking example of that. Chemists are trying to mimic living organisms because of the multitude of properties that might be implemented in synthetic systems ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

The AAP gene family for amino acid permeases contributes to development of the cyst nematode Heterodera schachtii in roots of Arabidopsis [PDF]

, 2013
The beet cyst nematode Heterodera schachtii is able to infect Arabidopsis plants and induce feeding sites in the root. These syncytia are the only source of nutrients for the nematodes throughout their life and are a nutrient sink for the host plant.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Amino and fatty acids composition of olive stones for the discrimination of 'Olea europaea' subsp. 'europaea' varieties

Mediterranean Botany, 2020
Few studies have reported the relationship between wild (Olea europaea L. subsp. europaea var. sylvestris) and cultivated (Olea europaea L. subsp. europaea var. europaea) olive trees by using diverse markers.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Amino acid release patterns of growing pig diets formulated with different dietary protein sources

Journal of Applied Animal Research, 2019
This study elucidated the dynamics of AA release in low-protein growing pig diets formulated with different protein sources. Four protein sources including soybean meal (SM), corn gluten meal (CGM), fish meal (FM) and fermented soybean meal (FSM) were ...

The effect of storage on the amino acids composition in potato tubers

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
The aim of this study was to investigate the effect of storage duration on amino acids content in potato tubers. Tubers of six cultivars were stored for 16 weeks. Crude protein was determined by the Kjeldahl method.
