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 ...

Surface fractal heterogeneity under microtopography during flow regime transition

Frontiers in Ecology and Evolution
While existing studies have explored interactions between microtopography and hydrodynamics, most failed to quantify the continuous dynamic responses of surface fractal heterogeneity along flow transitions triggered by microtopography and prolonged ...

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 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.

Surface Oxidation of Transition Metal Nitrides [PDF]

The Journal of Physical Chemistry C
The well-known Haber-Bosch process of NH3-production ishighly inefficient, with significant energy demand and high CO2 emissions. Alternative approaches like the electrochemical ammonia synthesis from N2 and H2 are attractive, but the sluggish nitrogen reduction reaction (NRR) that arises from the high energy input to activate stable N2 remains the ...
