Structural bases of peptidoglycan recognition by lysostaphin SH3b domain

Scientific Reports, 2019
Staphylococcus simulans lysostaphin cleaves pentaglycine cross-bridges between stem peptides in the peptidoglycan of susceptible staphylococci, including S. aureus.

Asymmetric Cu─N─Ru Bridgedsite Nanozyme‐Loaded Injectable Thermogel Boosts Cuproptosis‐Like Death for Multidrug‐Resistant Urinary Tract Infections

Advanced Science, EarlyView.
To address multidrug‐resistant urinary tract infections (MDR‐UTIs), we developed Cu‐ZIF8‐Ru nanozyme featuring an asymmetric Cu─N─Ru catalytic site. This unique structure enhances multienzyme‐mimetic activity, eradicating resistant bacteria by inducing a cuproptosis‐like death pathway through intracellular Cu2+ accumulation and energy depletion.

Fluorogenic D-amino acids enable real-time monitoring of peptidoglycan biosynthesis and high-throughput transpeptidation assays

Nature Chemistry, 2019
Peptidoglycan is an essential cell wall component that maintains the morphology and viability of nearly all bacteria. Its biosynthesis requires periplasmic transpeptidation reactions, which construct peptide crosslinkages between polysaccharide chains to

Hearing Loss: From Basic to Clinical Science

Advanced Science, EarlyView.
Abstract Hearing loss (HL) affects over 1.5 billion people globally, with genetic factors accounting for ≈50% of congenital cases. Therefore, HL has become a global health issue, driving extensive research from basic science to clinical applications. This Special Collection includes a total of 31 papers, among which 9 are review papers, 21 are research

Phage-Derived Peptidoglycan Degrading Enzymes: Challenges and Future Prospects for In Vivo Therapy

Viruses, 2018
Peptidoglycan degrading enzymes are of increasing interest as antibacterial agents, especially against multi-drug resistant pathogens. Herein we present a review about the biological features of virion-associated lysins and endolysins, phage-derived ...

Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

Journal of Applied Polymer Science, EarlyView.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Mechanism of lateral cell-wall expansion at a constant diameter in Bacillus subtilis

Nature Communications
In Escherichia coli, lateral cell-wall expansion during growth occurs by cross-linking of new glycan strands to the existing peptidoglycan network. However, it is unclear whether the same mechanism applies to other rod-shaped bacteria.

Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

Animal Research and One Health, EarlyView.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

Peptidoglycan LD-Transpeptidases

Antibiotics
LD-Transpeptidases (LDTs) are a widely conserved class of peptidoglycan (PG) crosslinking enzymes in bacteria. They are sometimes overlooked as they often act secondary to penicillin binding proteins (PBPs) under standard conditions.

Clinical Significance of Gut Microbiota Community Types for Long‐Term Response to Fecal Microbiota Transplantation in Patients With Psoriatic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Fecal microbiota transplantation (FMT) holds promises as a beneficial supplement to methotrexate in patients with psoriatic arthritis (PsA). We therefore investigated how gut bacterial signatures in patients and donor strain engraftment were associated with long‐term response to FMT.
