Pseudomonas aeruginosa gene PA4880 encodes a Dps-like protein with a Dps fold, bacterioferritin-type ferroxidase centers, and endonuclease activity

Frontiers in Molecular Biosciences
We report the biochemical, structural, and functional characterization of the protein coded by gene PA4880 in the P. aeruginosa PAO1 genome. The PA4880 gene had been annotated as coding a probable bacterioferritin.

Resonant X-ray diffraction studies on the charge ordering in magnetite

, 2006
Here we show that the low temperature phase of magnetite is associated with an effective, although fractional, ordering of the charge. Evidence and a quantitative evaluation of the atomic charges are achieved by using resonant x-ray diffraction (RXD ...

Coordination Geometry Tuning in a Single‐Atom Nanozyme to Mimic Metalloenzymes with Nonplanar Active Site

Advanced Science, EarlyView.
Correlation between coordination geometry and catalytic activity of carbonic anhydrase‐mimetic single‐atom Zn–N4 active sites is revealed. Among tetrahedral, distorted tetrahedral, and square‐planar Zn–N4 geometric configurations, the distorted tetrahedral Zn–N4 exhibits superior CO2 hydrolysis performance. This is attributed to increased Lewis acidity,

Discovering Uncharted Binding Pockets on E3 Ligases Leads to the Identification of FBW7 Allosteric Modulators

Advanced Science, EarlyView.
A computational approach to identify and characterize ligandable binding pockets on E3 ligases is presented. As a validation case, the first low‐micromolar small moleculesthat bind to the FBW7 E3 ligase are identified and confirmed to bind at the intended site.

Enhanced Bifunctional Electrocatalysis for Zinc‐Air Battery Using Porous Conductive Substrate with Abundant Anchoring Sites

Advanced Science, EarlyView.
A scalable nanocomposite synthesis is reported for a high‐performance bifunctional electrocatalyst by combining exfoliated layered materials—each active for OER and ORR—with a porous conductive substrate via high‐shear exfoliation. The electrocatalyst exhibits the lowest potential gap among reported transition metal‐based bifunctional catalysts.

Peptide Hormone‐Mediated Regulation of Plant Development and Environmental Adaptability

Advanced Science, EarlyView.
In this review, recent advances in understanding the roles of plant peptide hormones in regulating growth, reproduction, and environmental adaptability are systematically summarized. It further elucidates the challenges in studying these peptides, such as their low abundance, functional redundancy, and complex signaling mechanisms, and highlights their
