Regulation of the cell division hydrolase RipC by the FtsEX system in Mycobacterium tuberculosis
Nature Communications, 2023 The FtsEX complex regulates, directly or via a protein mediator depending on bacterial genera, peptidoglycan degradation for cell division. In mycobacteria and Gram-positive bacteria, the FtsEX system directly activates peptidoglycan-hydrolases by a ...

More than just lysins: peptidoglycan hydrolases tailor the cell wall. [PDF]
Curr Opin Microbiol, 2011 Enzymes that degrade the peptidoglycan (PG) cell wall layer called PG hydrolases or autolysins are often thought of as destructive forces. Phages employ them to lyse their host for the release of virion particles and some bacteria secrete them to eliminate (lyse) their competition.

Binding site‐shaped repeated sequences of bacterial wall peptidoglycan hydrolases [PDF]
FEBS Letters, 1994 The non‐catalytic C‐terminal regions of the N‐acetylmuramidase (lysozyme) of Clostridium acetobutylicum and N‐acetylmuramoyl(d‐lactyl)‐l‐alanine amidases CwlA of Bacillus subtilis, ORFL3 and CwlL of Bacillus licheniformis were previously reported to have similarities with the amino acid sequence of the non‐catalytic N‐terminal module of the ...

Carbohydrate recognition and lysis by bacterial peptidoglycan hydrolases
Current Opinion in Structural Biology, 2017 The major component of bacterial cell wall is peptidoglycan (PG), a complex polymer formed by long glycan chains cross-linked by peptide stems. PG is in constant equilibrium requiring well-orchestrated coordination between synthesis and degradation. The resulting cell-wall fragments can be recycled, act as messengers for bacterial communication, as ...

mBio, 2015 Bacterial SH3 (SH3b) domains are commonly fused with papain-like Nlp/P60 cell wall hydrolase domains. To understand how the modular architecture of SH3b and NlpC/P60 affects the activity of the catalytic domain, three putative NlpC/P60 cell wall ...

Reduced peptidoglycan synthesis capacity impairs growth of E. coli at high salt concentration
mBioGram-negative bacteria have a thin peptidoglycan layer between the cytoplasmic and outer membranes protecting the cell from osmotic challenges. Hydrolases of this structure are needed to cleave bonds to allow the newly synthesized peptidoglycan strands ...

A Proteolytic Complex Targets Multiple Cell Wall Hydrolases in
mBio, 2018 Carboxy-terminal processing proteases (CTPs) occur in all three domains of life. In bacteria, some of them have been associated with virulence. However, the precise roles of bacterial CTPs are poorly understood, and few direct proteolytic substrates have

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy
Advanced Materials, EarlyView.Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

eLife, 2019 Bacterial cells are encased in a peptidoglycan (PG) exoskeleton that protects them from osmotic lysis and specifies their distinct shapes. Cell wall hydrolases are required to enlarge this covalently closed macromolecule during growth, but how these ...
