Beta‐Lactam Antibiotics Promote Extracellular Vesicle Production of Staphylococcus aureus Through ROS‐Mediated Lipid Metabolic Reprogramming

Journal of Extracellular Vesicles, Volume 14, Issue 5, May 2025.
ABSTRACT Bacterial extracellular vesicles (EVs) are natural reservoirs of biological active substances. They exhibit promising application in developing bioproducts such as vaccine, drug‐delivery system and anticancer agent. However, the low yield of naturally secreted EVs during bacterial growth is a bottleneck factor that restricts EV applications ...

Design, Synthesis, and Antibacterial Evaluation of Pyrazole Pyrimidine Hybrids: Integrative In Vitro and In Silico Studies

ChemistrySelect, Volume 10, Issue 17, May 5, 2025.
This study synthesizes novel pyrimidine–pyrazole hybrids and evaluates their antimicrobial activity against bacterial pathogens by targeting penicillin‐binding protein 3 (PBP3). Several compounds show significant activity against E. faecium. Docking studies reveal strong binding with HMG‐CoA synthase, while in silico pharmacokinetic predictions ...

Non‐Membrane Active Peptide Resensitizes MRSA to β‐Lactam Antibiotics and Inhibits S. aureus Virulence

Advanced Science, Volume 12, Issue 15, April 17, 2025.
This work identifies a potent, non‐membrane active, and non‐toxic AMP termed GN1, which substantially resensitizes MRSA to multiple β‐lactam antibiotics at low concentrations. GN1 functions by suppressing MRSA‐associated resistance determinants, including penicillin‐binding protein 2a (PBP2a) and β‐lactamase.

Resistance to β-Lactam Antibiotics Conferred by Point Mutations in Penicillin-Binding Proteins PBP3, PBP4 and PBP6 in Salmonella enterica

PLoS ONE, 2014
Penicillin-binding proteins (PBPs) are enzymes responsible for the polymerization of the glycan strand and the cross-linking between glycan chains as well as the target proteins for β-lactam antibiotics. Mutational alterations in PBPs can confer resistance either by reducing binding of the antibiotic to the active site or by evolving a β-lactamase ...

Publisher Correction: Z-ring membrane anchors associate with cell wall synthases to initiate bacterial cell division

Nature Communications, 2019
The original version of this Article contained errors in Figures 1 and 3. In Fig. 1b, the label ‘IP-PBP3’ above the second of the three blots incorrectly read ‘IP-PBP1B’. In Fig.

Penicillin-binding Proteins (PBP) and Lmo0441 (a PBP-like protein) play a role in Beta-lactam sensitivity of Listeria monocytogenes

Gut Pathogens, 2009
While seven penicillin-binding proteins (PBPs) or PBP-like proteins have been identified either by radiolabelled penicillin binding studies or genomic analysis, only PBP3 has been considered of interest for Beta-lactams activity against Listeria ...

Occurrence and spread of carbapenemase‐producing Enterobacterales (CPE) in the food chain in the EU/EFTA. Part 1: 2025 update

EFSA Journal, Volume 23, Issue 4, April 2025.
Abstract Carbapenemase‐producing Enterobacterales (CPE) have been reported in the food chain in 14 out of 30 EU/EFTA countries. Commonly reported genes are blaVIM‐1, blaOXA‐48 and blaOXA‐181, followed by blaNDM‐5 and blaIMI‐1. Escherichia coli, target of most of the studies, Enterobacter cloacae complex, Klebsiella pneumoniae complex and Salmonella ...

Susceptibilities of cefiderocol, meropenem-xeruborbactam, cefepime-taniborbactam, aztreonam-avibactam, and sulbactam-durlobactam against imipenem-non-susceptible Gram-negative bacilli in Taiwan

International Journal of Infectious Diseases
Objectives: To evaluate susceptibilities of novel antibiotics against imipenem-non-susceptible (INS) Escherichia coli (INS-EC), Klebsiella pneumoniae (INS-KP), Acinetobacter baumannii (INS-AB), Pseudomonas aeruginosa (INS-PA) in Taiwan, and the potential

Identifying Novel Therapeutics for the Resistant Mutant “F533L” in PBP3 of Pseudomonas aeruginosa Using ML Techniques

ACS Omega
Pseudomonas aeruginosa (P. aeruginosa) is a highly infectious and antibiotic-resistant bacterium, which causes acute and chronic nosocomial infections. P. aeruginosa exhibits multidrug resistance due to the emergence of resistant mutants. The bacterium takes advantage of intrinsic and acquired resistance mechanisms to resist almost every antibiotic. To
