Essential and Non-Essential Metal Concentrations in Shrimps from Iskenderun Bay, Türkiye
Harran Üniversitesi Veteriner Fakültesi Dergisi, 2022 Contamination of the aquatic environment and living things with pollutants is increasing daily. Among these pollutants, heavy metals come to the forefront regarding toxicological and public health due to their widespread use, toxicity, and resistance to degradation, as well as accumulation and biomagnification in the food chain.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Endomembrane Reorganization Induced by Heavy Metals
Plants, 2020 Plant cells maintain plasmatic concentrations of essential heavy metal ions, such as iron, zinc, and copper, within the optimal functional range. To do so, several molecular mechanisms have to be committed to maintain concentrations of non-essential ...

Global Impact of Non-essential Heavy Metal Contaminants in Industrial Cannabis Bioeconomy [PDF]
, 2021 Abstract The intrinsic signatures of Cannabis species to bioaccumulate non-essential harmful heavy metals (HMs) are substantially determined by their high tolerance, weedy propensities, phenotypic plasticity attributes, and pedoclimatic stress adaptation in an ecological niche.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

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 ...

Impact of Aspiculuris tetraptera infection on metal homeostasis in Mus musculus [PDF]
Arquivo Brasileiro de Medicina Veterinária e ZootecniaHeavy metals are persistent contaminants that disrupt metabolic, enzymatic, and immune functions in exposed organisms. However, how intestinal parasites influence host metal homeostasis-particularly through sequestration of trace elements-remains ...
