Folds and activities of peptidoglycan amidases [PDF]
Bacterial peptidoglycan amidases are a large and diverse group of enzymes. During the last few years, genomic sequence information has accumulated to an extent such that lists of proven or predicted peptidoglycan amidases can now be expected to be fairly complete.

A new strategy for revitalizing aged biofilms using the elastic deformation of biomass‐based flexible carbon aerogel is proposed. The elastic deformation removes the nonelectrogenic bacteria and the dead electrogenic bacteria, as well as a lot of loosely bound extracellular polymer materials.

The structure of a resuscitation-promoting factor domain from Mycobacterium tuberculosis shows homology to lysozymes [PDF]
Resuscitation-promoting factor (RPF) proteins reactivate stationary-phase cultures of (G+C)-rich Gram-positive bacteria including the causative agent of tuberculosis, Mycobacterium tuberculosis.

In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...

This study developes a universal colorimetric ICA platform that integrates broad‐spectrum recognition by 4‐mercaptophenylboronic acid with dual signal enhancement—both colorimetric and catalytic—mediated by a biomimetic magnetic nanozyme. This platform, for the first time, enables simple, convenient, ultrasensitive, and simultaneous screening of ...

pH‐Responsive AIE Photosensitizers for Enhanced Antibacterial Therapy
This study develops DHTPA, a NIR fluorescent, pH‐responsive AIE photosensitizer that enhances photodynamic therapy for bacterial infections by promoting ROS generation in acidic environments, demonstrating effective antibacterial activity and accelerated wound healing in vitro and in vivo.

Enantiomer-specific isotope analysis of D- and L-alanine: Nitrogen isotopic hetero- and homogeneity in microbial and chemical processes [PDF]
Nitrogen isotopic hetero- and homogeneity of D-{\alpha}-alanine and L-{\alpha}-alanine were investigated in microbial processes in the domain Bacteria and in chemical processes in symmetric organic synthesis. D-alanine is an enantiomer that is physiologically essential for microbial growth and metabolic maintenance.

Alternate Germinants of C. Difficile, a Leading Hospital Pathogen
Clostridium difficile infections (CDI) are the leading nosocomial infections worldwide. Humans are asymptomatic carriers of C. difficile spores in the intestinal tract. The process known as germination occurs when otherwise harmless C.

Deficiency of RgpG causes major defects in cell division and biofilm formation, and deficiency of LytR-CpsAPsr family proteins leads to accumulation of cell wall antigens in culture medium by Streptococcus mutans [PDF]
Streptococcus mutans is known to possess rhamnose-glucose polysaccharide (RGP), a major cell wall antigen. S. mutans strains deficient in rgpG , encoding the first enzyme of the RGP biosynthesis

The peptidoglycan recognition proteins (PGRPs).
Peptidoglycan recognition proteins (PGRPs) are innate immunity molecules present in insects, mollusks, echinoderms, and vertebrates, but not in nematodes or plants. PGRPs have at least one carboxy-terminal PGRP domain (approximately 165 amino acids long), which is homologous to bacteriophage and bacterial type 2 amidases.
