Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Findings From the Pearl River Basin: Dissolved Oxygen Dominates Functional Trait Filtering and Diversity Patterns in Urban Rivers

Ecology and Evolution
Urbanization of river systems introduces novel environmental stressors—such as industrial pollutants and domestic wastewater—that impose selective pressures on aquatic species and reshape fish community structure.

Functional Characterization of Akt, a Serine/Threonine Kinase, in Tuta absoluta: A Key Regulator of Molting, Hormones, and Reproduction with Potential for RNAi Pest Control

Insects
Insect insulin signaling plays a central role in regulating development, metamorphosis, and reproduction, yet its mechanistic functions in the tomato leafminer, Tuta absoluta, a globally significant pest, remain poorly understood.

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

FEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

Use of genetically improved and alien species for aquaculture and conservation of aquatic biodiversity in Africa [PDF]

Aquaculture species are being domesticated and improved through genetic enhancement. Despite the benefits of improved fish in terms of increased production, there are risks associated with conservation of biodiversity when the introduced strains/species ...

Age-Stage, Two-Sex Life Table of Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) Experiencing Cadmium Stress

Insects
Cadmium in agricultural soils has emerged as a substantial threat to crop health and yields through its bioaccumulation along the food chain, with further repercussions for the growth, development, and population dynamics of herbivorous insects.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Trade, the Damage from Alien Species, and the Effects of Protectionism Under Alternate Market Structures [PDF]

We first construct three measures of the expected damage from the unintentional introduction of alien species into a country called Home. We then focus on four market structures.

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

Effect of nanoparticles on the growth of okra cultivated in soil affected by rocky desertification

Scientific Reports
This study investigated the influence of various nanoparticles (NPs), including carbon-based NPs, Al2O3-NPs, SiO2-NPs, and TiO2-NPs, on the growth and physiology of okra plants cultivated in soil impacted by rocky desertification.
