Trait-mediated insect colonization of newly established grassland strips in agricultural landscapes

Basic and Applied Ecology
Restoring grasslands in agroecosystems through the establishment of grassland and flowering strips has been demonstrated to promote insects. However, the development of the functional composition of insect assemblages in newly established grassland ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Potential Invasion Risk of Empoasca fabae in China Under CMIP6 Scenarios: Integrating Climatic Suitability and Host Plant Distribution

Agronomy
Empoasca fabae (Harris) is a destructive migratory pest threatening potato cultivation globally. As climate change may facilitate its invasion into China, the world’s largest potato producer, projecting its potential range is critical for early warning ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

The new permanent establishment

, 2023
The PE is a century-old concept with a fundamental role in the international taxation system via the fair allocation of taxing rights over cross-border business profits within the source-residence principles equilibrium, as a vital threshold for source taxation. Throughout its existence, this pivotal element has relied on its founding principles, which

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...
