ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Selected properties of cobalt-contaminated soil following the application of neutralising substances

Environmental Protection and Natural Resources, 2016
The aim of the study was to determine the influence of increasing cobalt soil contamination (0 mg·kg−1, 20 mg·kg−1, 40 mg·kg−1, 80 mg·kg−1, 160 mg·kg−1, 320 mg·kg−1) after the application of neutralising substances on selected soil properties.

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 ...

Relationship between acidity and chemical properties of brazilian soils

Scientia Agricola, 2003
In soils of tropical climate regions the high acidity and the presence of exchangeable aluminum (Al3+), associated to low fertility, are the main restrainting factors for agricultural production.

Ion Exchange Chromatography of Monochloroacetic Acid and Monoiodoacetic acid

Journal of Synthetic Organic Chemistry, Japan, 1960
A process of separatory determination of monochioroacetic acid (M. C. A.) and monoiodoacetic acid (M. I. A.) by use of ion exchange resin has been investigated. A strongly basic R-NO3 type resin, Amberlite IRA-410, of 100-150 mesh size was used for the test.The adsorbed acids were liberated by using NaNO3 as a liberating agent in order of M. C. A.and M.

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 ...

Amino acid neurotransmitters in the CNS

FEBS Letters, 1986
D‐Aspartate exchange, defined as amino acid‐stimulated D‐[3H]aspartate efflux, was investigated in a preparation of rat brain synaptosomes. The efflux of radiolabelled D‐aspartate was found to be enhanced by micromolar concentrations of externally added D‐ and L‐aspartate, L‐glutamate, L‐cysteate.and L‐cysteinesulphinate.

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.

Phosphorus fraction transformation and soil acidity mitigation through integration of water hyacinth biochar with organic and synthetic phosphorus sources in acidic soil

Frontiers in Environmental Science
Phosphorus (P) deficiency is a major problem in acidic and tropical soils, including in Ethiopia, because more than 80% of P derived from synthetic fertilizers becomes fixed and unavailable.
