Dynamic capsule restructuring by the main pneumococcal autolysin LytA in response to the epithelium
Nature Communications, 2016 Pneumococci produce a carbohydrate capsule that protects them against components of the host immune system but sensitizes them to host antimicrobial peptides.

ChemCatChem, Volume 18, Issue 10, 27 May 2026.Bacillus subtilis PdaC is the first peptidoglycan deacetylase able to act in reverse, acetylating a glucosamine oligomer (chitopentaose) with a pattern of acetylation mirroring the natural deacetylation reaction with unique final regioselectivity, acetylating all but the reducing end of D5.

Frontiers in Microbiology, 2015 Autolysis is a widespread phenomenon in bacteria. In batch fermentation of Clostridium acetobutylicum ATCC 824, there is a spontaneous large-scale autolysis phenomenon with significant decrease of cell density immediately after exponential phase.

Insertional inactivation of the major autolysin gene of Streptococcus pneumoniae [PDF]
Journal of Bacteriology, 1988 The lytA gene encoding the major pneumococcal autolysin (N-acetylmuramoyl-L-alanine amidase) was inactivated by inserting the 2-kilobase MspI fragment of pE194 containing the staphylococcal ermC gene. Stable autolysis-deficient (Lyt-) mutants and their isogenic Lyt+ parents were used in experiments designed to test possible physiological functions of ...

ssRNA bacteriophage metagenomes reveal a diverse set of novel protein families
Protein Science, Volume 35, Issue 5, May 2026.Abstract The bacteriophages with single‐stranded RNA (ssRNA) genomes (class Leviviricetes) are among the simplest known viruses that encode only three core proteins: a receptor‐binding protein, a capsid protein, and an RNA‐dependent RNA polymerase. The number of isolated ssRNA phages has remained very low, but the accumulating RNA metagenome data have ...

The Cell Surface, 2018 The bacterial cell wall is in part composed of the peptidoglycan (PG) layer that maintains the cell shape and sustains the basic cellular processes of growth and division. The cell wall of Gram-positive bacteria also carries teichoic acids (TAs). In this

Lactobacillus acidophilus Autolysins Inhibit Helicobacter pylori In Vitro
Current Microbiology, 2001 Antibacterial activity of 17 strains of lactobacilli was tested against 10 strains of H. pylori. The inhibition observed was related to the acid production and the low pH attained. No relationship between CagA phenotype of H. pylori strains and tolerance to lactic acid was observed. In mixed cultures, L. acidophilus CRL 639 showed an autolytic behavior

Les autolysines des bactéries lactiques [PDF]
Le Lait, 1996 Les autolysines sont definies comme des enzymes bacteriennes endogenes capables d'hydrolyser le peptidoglycane, qui est le constituant majeur et essentiel de la paroi. Leur action peut donc induire la lyse bacterienne. Un certain nombre d'autolysines ont ete caracterisees au niveau moleculaire chez differentes bacteries.

Partial characterization of a major autolysin from Mycobacterium phlei [PDF]
Microbiology, 1999 Autolytic enzyme profiles of fast- and slow-growing mycobacteria were examined using SDS-PAGE zymography with incorporated mycobacterial peptidoglycan sacculi as substrate. Each species tested (Mycobacterium phlei, Mycobacterium smegmatis, Mycobacterium aurum, Mycobacterium fortuitum and Mycobacterium kansasii) appeared to produce a different set of ...

Bacterial Extracellular Vesicles in Biomedical Research and Clinical Translation
Microbial Biotechnology, Volume 19, Issue 4, April 2026.Bacterial membrane vesicle biomedical applications. ABSTRACT Bacterial Extracellular Vesicles (bEVs) are lipid (single‐ or double‐bilayer) nanostructures secreted by virtually all bacteria that play fundamental roles in intercellular communication and have emerged as powerful, multifunctional tools in biomedicine. Their intrinsic ability to encapsulate
