Secreted antigen A peptidoglycan hydrolase is essential for Enterococcus faecium cell separation and priming of immune checkpoint inhibitor therapy [PDF]
Enterococcus faecium is a microbiota species in humans that can modulate host immunity (Griffin and Hang, 2022), but has also acquired antibiotic resistance and is a major cause of hospital-associated infections (Van Tyne and Gilmore, 2014).

Multilevel Regulation of Peptidoglycan Dynamics in Bacteria: From Molecular Mechanisms to Applied Perspectives [PDF]
Peptidoglycan, a crucial constituent of the bacterial cell envelope, is essential for maintaining cellular integrity and morphology. Elucidating the regulatory processes that coordinate its biosynthesis and turnover not only addresses a fundamental ...

LytF contributes to pilus extrusion during natural competence in Streptococcus sanguinis SK36 [PDF]
Streptococci may enter a physiological state called competence, during which they express a specific set of genes required for exogenous DNA uptake and its subsequent integration into the genome through homologous recombination.

Asymmetric peptidoglycan editing generates cell curvature in Bdellovibrio predatory bacteria
Cells of the predatory bacterium Bdellovibrio bacteriovorus, which invades and replicates within the periplasm of other bacteria, have a characteristic curved rod shape. Here, Banks et al.

Archaea produce peptidoglycan hydrolases that kill bacteria
The social life of archaea is poorly understood. In particular, even though competition and conflict are common themes in microbial communities, there is scant evidence documenting antagonistic interactions between archaea and their abundant prokaryotic brethren: bacteria. Do archaea specifically target bacteria for destruction? If

Acd, a peptidoglycan hydrolase of Clostridium difficile with N-acetylglucosaminidase activity
A gene encoding a putative peptidoglycan hydrolase was identified by sequence similarity searching in the Clostridium difficile 630 genome sequence, and the corresponding protein, named Acd (autolysin of C. difficile) was expressed in Escherichia coli. The deduced amino acid sequence of Acd shows a modular structure with two main domains: an N-terminal

Most of the gene clusters encoding multiprotein complexes of the bacterial cell envelope, such as conjugation and secretion systems, Type IV pili and flagella, bear a gene encoding an enzyme with peptidoglycan hydrolase activity. These enzymes are usually glycoside hydrolases that cleave the glycan chains of the peptidoglycan.

Ser/Thr Kinase-Dependent Phosphorylation of the Peptidoglycan Hydrolase CwlA Controls Its Export and Modulates Cell Division in Clostridioides difficile. [PDF]
International audienceCell growth and division require a balance between synthesis and hydrolysis of the peptidoglycan (PG). Inhibition of PG synthesis or uncontrolled PG hydrolysis can be lethal for the cells, making it imperative to control ...
