Distinct Amino Acid Availability-Dependent Regulatory Mechanisms of MepS and MepM Levels in Escherichia coli

open access: yesFrontiers in Microbiology, 2021
Peptidoglycan (PG) hydrolases play important roles in various aspects of bacterial physiology, including cytokinesis, PG synthesis, quality control of PG, PG recycling, and antibiotic resistance. However, the regulatory mechanisms of their expression are

Asymmetric peptidoglycan editing generates cell curvature in Bdellovibrio predatory bacteria

open access: yesNature Communications, 2022
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.

Peptidoglycan hydrolases-potential weapons against Staphylococcus aureus [PDF]

open access: yesApplied Microbiology and Biotechnology, 2012
Bacteria of the genus Staphylococcus are common pathogens responsible for a broad spectrum of human and animal infections and belong to the most important etiological factors causing food poisoning. Because of rapid increase in the prevalence of isolation of staphylococci resistant to many antibiotics, there is an urgent need for the development of new

Peptidoglycan Hydrolase Fusions Maintain Their Parental Specificities [PDF]

open access: yesApplied and Environmental Microbiology, 2006
ABSTRACT The increased incidence of bacterial antibiotic resistance has led to a renewed search for novel antimicrobials. Avoiding the use of broad-range antimicrobials through the use of specific peptidoglycan hydrolases (endolysins) might reduce the incidence of antibiotic-resistant pathogens worldwide.

Genetic Evidence for Distinct Functions of Peptidoglycan Endopeptidases in Escherichia coli

open access: yesFrontiers in Microbiology, 2020
Peptidoglycan (PG) is an essential component of the bacterial exoskeleton that plays a pivotal role in the maintenance of cell shape and resistance to cell lysis under high turgor pressures.

Divergent Effects of Peptidoglycan Carboxypeptidase DacA on Intrinsic β-Lactam and Vancomycin Resistance

open access: yesMicrobiology Spectrum, 2022
Vancomycin and β-lactams are clinically important antibiotics that inhibit the formation of peptidoglycan cross-links, but their binding targets are different.

A new peptidoglycan hydrolase in Streptococcus pneumoniae [PDF]

open access: yesFEMS Microbiology Letters, 1986
The use of a mutant of Streptococcus pneumoniae deleted in the lytA gene coding for the N-acetyl-muramyl-l-alanine amidase, and therefore devoid of any amidase, has allowed the identification of a new murein hydrolase activity in this bacterium. This enzyme (or enzymes) acted as an autolysin when the cultures were grown at 30°C.

Enterococcus faecium secreted antigen A generates muropeptides to enhance host immunity and limit bacterial pathogenesis

open access: yeseLife, 2019
We discovered that Enterococcus faecium (E. faecium), a ubiquitous commensal bacterium, and its secreted peptidoglycan hydrolase (SagA) were sufficient to enhance intestinal barrier function and pathogen tolerance, but the precise biochemical mechanism ...

A second endolysin gene is fully embedded in-frame with the lysA gene of mycobacteriophage Ms6. [PDF]

open access: yesPLoS ONE, 2011
Mycobacteriophages are dsDNA viruses that infect mycobacterial hosts. The mycobacteriophage Ms6 accomplishes lysis by producing two cell wall hydrolytic enzymes, Lysin A (LysA) that possesses a central peptidoglycan recognition protein (PGRP) super ...

Two Pfam protein families characterized by a crystal structure of protein lpg2210 from Legionella pneumophila. [PDF]

open access: yes, 2013
BackgroundEvery genome contains a large number of uncharacterized proteins that may encode entirely novel biological systems. Many of these uncharacterized proteins fall into related sequence families. By applying sequence and structural analysis we hope
