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 ...

Low-energy pion-nucleus optical potentials

, 1973
Discusses the local and non-local pion-nucleus optical potentials. It is found that the local potential becomes non-local when two-nucleon correlations are included.

7Li(15N,14C)8Be reaction and 13,14C + 8Be nuclei interactions

Ядерна фізика та енергетика, 2017
Angular distributions of the 7Li(15N,14C)8Be reaction were measured at the energy Elab(15N) = 81 MeV. The reaction data were analyzed within coupled-reaction-channels (CRC) method. The 7Li + 15N elastic and inelastic scattering and the more important one-

40Ar+p Elastic scattering measurement at energies near the Coulomb barrier for optical potential study

Results in Physics
Nuclear optical potentials are essential for calculating nuclear cross-sections and for probing nuclear structures and dynamics. The phenomenological global optical model potentials (pGOMPs), such as Koning–Delaroche (KD) and Perey–Perey (PP) potentials,

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

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 ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Optical Remote Sensing Potentials for Looting Detection

Geosciences, 2017
Looting of archaeological sites is illegal and considered a major anthropogenic threat for cultural heritage, entailing undesirable and irreversible damage at several levels, such as landscape disturbance, heritage destruction, and adverse social impact.
