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 ...

Can asymmetries account for the empirical failure of the Fisher effect in South Africa? [PDF]
This paper investigates whether unobserved asymmetries can account for irregularities in the Fisher effect for the exclusive case of South Africa. This objective is attained by investigating unit roots within a threshold auto-regressive (TAR) models and ...

Neutralization of the PTX3/CD44 axis suppresses TGF‐β1 signaling in kidney fibrosis
FEBS Letters, EarlyView.This study investigates how the PTX3/CD44 axis promotes kidney fibrosis by activating TGF‐β1 signaling. We demonstrate that the neutralizing antibody WHC‐001 effectively inhibits this pathway, suppressing myofibroblast activation and partial epithelial–mesenchymal transition (EMT).

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 ...

The Effect of Myopia on Contrast Thresholds
Investigative Opthalmology & Visual Science, 2007 To examine the relationship between the degree of myopia and foveally measured contrast thresholds.Monocular thresholds for positive and negative contrast were obtained from 60 myopes (-1.0 to -8.0 D) and 20 emmetropes of similar age. The contrast thresholds were measured at different background luminance levels, photopic and mesopic, by using a visual
