Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Proteome‐wide identification of mycobacterial pupylation targets

Molecular Systems Biology, 2010
Mycobacteria use a unique system for covalently modifying proteins based on the conjugation of a small protein, referred to as prokaryotic ubiquitin‐like protein (PUP). In this study, we report a proteome‐wide analysis of endogenous pupylation targets in

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Targeted anticancer pre-vinylsulfone covalent inhibitors of carbonic anhydrase IX

eLife
We designed novel pre-drug compounds that transform into an active form that covalently modifies particular His residue in the active site, a difficult task to achieve, and applied to carbonic anhydrase (CAIX), a transmembrane protein, highly ...

Enhanced proton conduction by post-synthetic covalent modification in a porous covalent framework

, 2017
Ether linkage based chemically stable porous covalent framework has been synthesized which upon post-synthetic modification presents a remarkably high proton conductivity (∼0.026 S cm−1) with an ∼130 fold enhancement compared to parent compound.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Covalent modifications of histones during mitosis and meiosis [PDF]

Cell Cycle, 2009
Higher order chromosome structures are the hallmark of mitotic and meiotic cells. Chromatin condensation and compaction are essential for rapid chromosome congression and accurate chromosome segregation during cell division. The core histones possess tails at their amino-termini. These tails, which extend from the surface of the nucleosomes, are highly

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Covalent Modification Regulates Ligand Binding to Receptor Complexes in the Chemosensory System of Escherichia coli

, 2000
In the Escherichia coli chemosensory pathway, receptor modification mediates adaptation to ligand. Evidence is presented that covalent modification influences ligand binding to receptors in complexes with CheW and the kinase CheA.

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

Advanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
