Nod1 signaling overcomes resistance of S. pneumoniae to opsonophagocytic killing [PDF]

open access: yes, 2007

Indistinguishability and identifiability of kinetic models for the MurC reaction in peptidoglycan biosynthesis [PDF]

open access: yes, 2009
An important question in Systems Biology is the design of experiments that enable discrimination between two (or more) competing chemical pathway models or biological mechanisms.

Synthesis and application of peptidoglycan derivatives to study the recognition and activation of the innate immune receptor NOD2

open access: yes, 2022
Grimes, Catherine LeimkuhlerThe bacterial cell wall fragment, muramyl dipeptide, has been recognized since the 1970s as the minimal fragment necessary to initiate an innate immune response.

Resistance to mucosal lysozyme compensates for the fitness deficit of peptidoglycan modifications by Streptococcus pneumoniae. [PDF]

open access: yesPLoS Pathogens, 2008
The abundance of lysozyme on mucosal surfaces suggests that successful colonizers must be able to evade its antimicrobial effects. Lysozyme has a muramidase activity that hydrolyzes bacterial peptidoglycan and a non-muramidase activity attributable to ...

Characterization of Pseudomonas aeruginosa l,d-Transpeptidases and Evaluation of Their Role in Peptidoglycan Adaptation to Biofilm Growth

open access: yesMicrobiology Spectrum, 2023
Peptidoglycan is an essential component of the bacterial cell envelope that sustains the turgor pressure of the cytoplasm, determines cell shape, and acts as a scaffold for the anchoring of envelope polymers such as lipoproteins.

Peptidoglycan Composition in Neisseria [PDF]

open access: yes, 2019
The composition of Neisseria peptidoglycan has been of scientific interest for over four decades. Initial investigations focused on discovering the mechanisms causing rising rates of antibiotic resistance in N. gonorrhoeae by determining differences in peptidoglycan composition in penicillin susceptible and resistant strains.

Peptidoglycan: Structure, Synthesis, and Regulation

open access: yes, 2021
Peptidoglycan is a defining feature of the bacterial cell wall. Initially identified as a target of the revolutionary beta-lactam antibiotics, peptidoglycan has become a subject of much interest for its biology, its potential for the discovery of novel ...

Dual strategies for peptidoglycan discrimination by peptidoglycan recognition proteins (PGRPs) [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
The innate immune system constitutes the first line of defense against microorganisms in both vertebrates and invertebrates. Although much progress has been made toward identifying key receptors and understanding their role in host defense, far less is known about how these receptors recognize microbial ligands. Such studies have been severely hampered

Peptidoglycan precursor synthesis along the sidewall of pole-growing mycobacteria

open access: yeseLife, 2018
Rod-shaped mycobacteria expand from their poles, yet d-amino acid probes label cell wall peptidoglycan in this genus at both the poles and sidewall. We sought to clarify the metabolic fates of these probes.

Removal of peptidoglycan and inhibition of active cellular processes leads to daptomycin tolerance in Enterococcus faecalis.

open access: yesPLoS ONE, 2021
Daptomycin is a cyclic lipopeptide antibiotic used in the clinic for treatment of severe enterococcal infections. Recent reports indicate that daptomycin targets active cellular processes, specifically, peptidoglycan biosynthesis. Within, we examined the
