Anchoring of Surface Proteins to the Cell Wall of Staphylococcus aureus: sortase catalyzed in vitro transpeptidation reaction using LPXTG peptide and NH2-Gly3 substrates [PDF]
, 2000 Staphylococcus aureus sortase anchors surface proteins to the cell wall envelope by cleaving polypeptides at the LPXTG motif. Surface proteins are linked to the peptidoglycan by an amide bond between the C-terminal carboxyl and the amino group of the ...

CD9‐association with PIP2 areas is regulated by a CD9 salt bridge
FEBS Open Bio, EarlyView.The tetraspanin CD9 has an intracellular salt bridge. If CD9 opens, open‐CD9 moves from PIP2‐rich areas to regions populated by its interaction partner EWI‐2. Hence, the state of the salt bridge regulates the distribution of CD9 and by this CD9‐EWI‐2 complex formation.

FEBS Open Bio, EarlyView.In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

Organometallic Palladium Reagents for Cysteine Bioconjugation
Nature, 2015 Reactions based on transition metals have found wide use in organic synthesis, in particular for the functionalization of small molecules. However, there are very few reports of using transition-metal-based reactions to modify complex biomolecules, which

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae
FEBS Open Bio, EarlyView.A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.
