Gold Nanoparticle Capped Citrate as a Ligand for Chromium(III) Ion: Optimization and Its Application in Contaminated Tap Water

Indonesian Journal of Chemistry, 2022
Citrate-capped gold nanoparticle (GNP) was used as a ligand for chromium chelating, and chromium ions reaction led to GNP aggregation. The color change of GNP by aggregation in the presence of chromium is a simple and rapid colorimetric test for these ...

Single-Cell Discrimination of Citrate/Isocitrate Isomers via Induced Nano-Electrospray Ionization Tandem Mass Spectrometry

Zhipu Xuebao
Citrate (CA) and isocitrate (ICA) are key isomeric metabolites in the tricarboxylic acid (TCA) cycle, synthesized sequentially from acetyl-CoA and oxaloacetate, with isomerization catalyzed by aconitase 2 (ACO2). The dynamic balance between CA and ICA is

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.

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.

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 ...
