Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Synergistic Optimization of Double Layer Capacitance and Pseudocapacitance of Activated Carbon by Nickel Oxide Loading

International Journal of Electrochemical Science, 2019
Low concentration basic nickel carbonate is selected to load nickel oxide on sargassum-based activated carbon to improve the gravimetric capacitance of activated carbon electrode materials. Based on the pyrolysis characteristics of basic nickel carbonate,

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

One-step thermochemical activation of waste wood for micropollutant adsorption: Optimisation via design of experiments

Case Studies in Chemical and Environmental Engineering
The increasing generation of waste wood (WW) and the demand for activated carbon (AC) in wastewater treatment highlight the need for sustainable alternatives. WW was converted into AC via one-step thermochemical activation using carbon dioxide, steam, or

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Controlling sub-nanometer pore-entrance size enables kinetic separation of Li+, Na+, and K+ in capacitive deionization

Carbon Trends
Efficient recovery of lithium and potassium from saline resources is vital for energy storage and global food security. We present a novel capacitive deionization (CDI) approach employing carbon molecular sieve (CMS) electrodes with precisely tuned sub ...
