In Vivo Cross‐Linking Sheds Light on the Salmonella Divisome in Which PBP3 and PBP3SAL Compete for Occupancy

Molecular Microbiology, Volume 122, Issue 5, Page 797-818, November 2024.
Salmonella encodes two peptidoglycan synthases, PBP3 and PBP3SAL, which can promote cell division independently. This study shows by in vivo cross‐linking and proteomics that PBP3 and PBP3SAL do not interact in the division complex and that ~40 proteins may associate direct or indirectly to these enzymes, including expected divisome components and new ...

Comprehensive Antigen Screening Identifies Moraxella catarrhalis Proteins That Induce Protection in a Mouse Pulmonary Clearance Model [PDF]

, 2013
Moraxella catarrhalis is one of the three most common causative bacterial pathogens of otitis media, however no effective vaccine against M. catarrhalis has been developed so far. To identify M.

Peptidoglycan Endopeptidase PBP7 Facilitates the Recruitment of FtsN to the Divisome and Promotes Peptidoglycan Synthesis in Escherichia coli

Molecular Microbiology, Volume 122, Issue 5, Page 743-756, November 2024.
The peptidoglycan (PG) hydrolase PBP7 localizes to both the lateral cell envelope and midcell in Escherichia coli, and its midcell localization is dependent on an active divisome. PBP7 influences the timing of FtsZ and FtsN assembly within the divisome. In the absence of PBP7, FtsN assembly is slower and septal PG synthesis is reduced in the absence of

Lytic transglycosylases RlpA and MltC assist in Vibrio cholerae daughter cell separation [PDF]

Molecular Microbiology, 2019
Summary The cell wall is a crucial structural feature in the vast majority of bacteria and comprises a covalently closed network of peptidoglycan (PG) strands. While PG synthesis is important for survival under many conditions, the cell wall is also a dynamic structure, undergoing degradation and remodeling by ...

Breaking barriers: pCF10 type 4 secretion system relies on a self-regulating muramidase to modulate the cell wall

mBio
Conjugative type 4 secretion systems (T4SSs) are the main driver for the spread of antibiotic resistance genes and virulence factors in bacteria.

Bacterial extracellular vesicles as intranasal postbiotics: Detailed characterization and interaction with airway cells

Journal of Extracellular Vesicles, Volume 13, Issue 10, October 2024.
This study investigates Escherichia coli A0 34/86 (EcO83), a probiotic strain known for its ability to prevent infections and diarrhoea in newborns and reduce allergic airway inflammation in mice. Although live probiotic bacteria are effective, they also harbour certain risks, such as possible infection and gene transfer.

Toxin release mediated by the novel autolysin Cwp19 in Clostridium difficile

Microbial Cell, 2018
Clostridium difficile, also known as Clostriodioides difficile, is a Gram positive, spore-forming bacterium and a leading cause of antibiotic-associated diarrhea in nosocomial environments. The key virulence factors of this pathogen are two toxins, toxin
