Factors essential for L,D-transpeptidase-mediated peptidoglycan cross-linking and β-lactam resistance in Escherichia coli

eLife, 2016
The target of β-lactam antibiotics is the D,D-transpeptidase activity of penicillin-binding proteins (PBPs) for synthesis of 4→3 cross-links in the peptidoglycan of bacterial cell walls.

A Wearable Electrochemical Biosensor for Salivary Detection of Periodontal Inflammation Biomarkers: Molecularly Imprinted Polymer Sensor with Deep Learning Integration

Advanced Science, EarlyView.
A wearable electrochemical biosensor integrated into a smart mouthguard enables the non‐invasive detection of salivary MMP‐8 for early monitoring of periodontal inflammation. Featuring a molecularly imprinted polymer‐based sensing layer, the platform offers high cytokine selectivity and impedance‐driven sensitivity. Combining wireless connectivity with

Distinct Spatiotemporal Dynamics of Peptidoglycan Synthesis between Mycobacterium smegmatis and Mycobacterium tuberculosis

mBio, 2017
Peptidoglycan (PG), a polymer cross-linked by d-amino acid-containing peptides, is an essential component of the bacterial cell wall. We found that a fluorescent d-alanine analog (FDAA) incorporates chiefly at one of the two poles in Mycobacterium ...

Boosting the Antimicrobial Activity of Quaternary Ammonium Photosensitizers by Janus‐Type AIE Luminogens

Aggregate, EarlyView.
Novel quaternary ammonium AIE luminogens (AIEgens) with symmetric and Janus structures are rationally designed and prepared for bacteria killings. The integration of experimental and theoretical studies discloses that the Janus‐type AIEgen interacts better with bacterial membranes and shows stronger membrane perturbation, demonstrating superior ...

Nicht‐Amphiphile Antimikrobielle Polymere

Angewandte Chemie, EarlyView.
Gänzlich nicht‐amphiphile antimikrobielle Polymere (APs), die deutliche Bioaktivität und ausgezeichnete Selektivitäten zeigen, werden vorgestellt. Die Bedeutung von Wasserstoffbrücken‐Bindungen wird durch die Segregation von APs an bakteriellen Membranmodellen und Bakterien hervorgehoben. Dieses Verhalten wurde für amphiphile Polymere nicht beobachtet.

Non‐Amphiphilic Antimicrobial Polymers

Angewandte Chemie International Edition, EarlyView.
Completely non‐amphiphilic antimicrobial polymers (APs) that possess significant bioactivity and excellent selectivity are presented. The importance of hydrogen‐bonding interactions is highlighted by segregation of APs on bacterial membrane models and bacteria, a behavior absent in amphiphilic polymers.

The hidden base of the iceberg: gut peptidoglycome dynamics is foundational to its influence on the host

Gut Microbes
The intestinal microbiota of humans includes a highly diverse range of bacterial species. All these bacteria possess a cell wall, composed primarily of the macromolecule peptidoglycan.

Self‐Crosslinkable Bacterial Cellulose/Chitosan/Pectin Injectable Hydrogels: Design, Characterization and Preliminary Biological Performance

Journal of Applied Polymer Science, EarlyView.
Bio‐injectable hydrogel. ABSTRACT In this study, multifunctional polysaccharide‐based injectable hydrogels were developed using chitosan (CS) and dialdehyde bacterial cellulose (D‐BC), interpenetrated with pectin (PT). The hydrogels exhibited rapid gelation, good water retention, and injectability under physiological conditions.
