APE1 Activity is Controlled by Non‐G‐Quadruplex Conformations in Single‐ and Double‐Stranded G‐Quadruplex Constructs

open access: yesChemistry – A European Journal, EarlyView.
G‐quadruplex (G4) folding in DNA is inhibitory to AP endonuclease, although the protein still binds well to G4s. Curiously, partially folded G‐rich sequences, possibly transient hairpins, containing AP are very good substrates for cleavage by APE1. Herein, the enzyme activity and G4 folding are studied in single‐stranded vs. duplex contexts.

Development of tCAP(N3): Affinity Peptide‐Aided, pH‐Triggered Strategy for Site‐Specific Native IgG Modification

open access: yesChemistry – A European Journal, EarlyView.
The tCAP(N3) reagent, featuring a stable and self‐activating precursor, enables site‐specific conjugation of native IgGs. This Fc‐affinity peptide approach selectively transfers an Ac‐Lys(N3)‐Gly‐Gly payload to Lys248, producing divalently azidated antibody while preserving its biological function.

Interfacial adsorption characteristics of surfactant‐modified nanoparticles: Equilibrium and dynamic effects of salinity at the oil–water interface

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...
