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 ...

Purification and properties of a membrane-bound lytic transglycosylase from Escherichia coli [PDF]

Journal of Bacteriology, 1994
A membrane-bound lytic transglycosylase (Mlt) has been solubilized in the presence of 2% Triton X-100 containing 0.5 M NaCl from membranes of an Escherichia coli mutant that carries a deletion in the slt gene coding for a 70-kDa soluble lytic transglycosylase (Slt70).

Structure of MltG from Mycobacterium abscessus reveals structural plasticity between composed domains

IUCrJ
MltG, a membrane-bound lytic transglycosylase, has roles in terminating glycan polymerization in peptidoglycan and incorporating glycan chains into the cell wall, making it significant in bacterial cell-wall biosynthesis and remodeling.

The Pathogenic Neisseria Use a Streamlined Set of Peptidoglycan Degradation Proteins for Peptidoglycan Remodeling, Recycling, and Toxic Fragment Release

Frontiers in Microbiology, 2019
Neisseria gonorrhoeae and Neisseria meningitidis release peptidoglycan (PG) fragments from the cell as the bacteria grow. For N. gonorrhoeae these PG fragments are known to cause damage to human Fallopian tube tissue in organ culture that mimics the ...

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

Characterization of the Nonconserved hpaB-hrpF Region in the hrp Pathogenicity Island from Xanthomonas campestris pv. vesicatoria

Molecular Plant-Microbe Interactions, 2007
The interaction of the gram-negative phytopathogenic bacterium Xanthomonas campestris pv. vesicatoria with its host plants pepper and tomato is mediated by a type III secretion (T3S) system that translocates bacterial effector proteins into the plant ...

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.

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.

A global regulatory system links virulence and antibiotic resistance to envelope homeostasis in Acinetobacter baumannii. [PDF]

PLoS Pathogens, 2018
The nosocomial pathogen Acinetobacter baumannii is a significant threat due to its ability to cause infections refractory to a broad range of antibiotic treatments.

' Lactobacillus fermentum ' 3872 genome sequencing reveals plasmid and chromosomal genes potentially involved in a probiotic activity. [PDF]

, 2015
In this report we describe a ' Lactobacillus fermentum ' 3872 plasmid (pLF3872) not previously found in any other strain of this species. The analysis of the complete sequence of this plasmid revealed the presence of a gene encoding a large collagen ...
