Microbiology 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.

Dynamics of the bacterial flagellar motor with multiple stators [PDF]
PNAS 106 (2009) 3746-3751, 2009 The bacterial flagellar motor drives the rotation of flagellar filaments and enables many species of bacteria to swim. Torque is generated by interaction of stator units, anchored to the peptidoglycan cell wall, with the rotor. Recent experiments [Yuan, J. & Berg, H. C.

Genetics of Peptidoglycan Biosynthesis
Microbiology Spectrum, 2014 ABSTRACT The complex cell envelope is a hallmark of mycobacteria and is anchored by the peptidoglycan layer, which is similar to that of Escherichia coli and a number of other bacteria but with modifications to the monomeric units and other structural complexities that are likely related to a role for the ...

Activities and regulation of peptidoglycan synthases [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2015 Peptidoglycan (PG) is an essential component in the cell wall of nearly all bacteria, forming a continuous, mesh-like structure, called the sacculus, around the cytoplasmic membrane to protect the cell from bursting by its turgor. Although PG synthases, the penicillin-binding proteins (PBPs), have been studied for 70 years, useful

Peptidoglycan precursor synthesis along the sidewall of pole-growing mycobacteria
eLife, 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.

How innate immunity proteins kill bacteria and why they are not prone to resistance [PDF]
, 2017 Recent advances on antibacterial activity of peptidoglycan recognition proteins (PGRPs) offer some insight into how innate immunity has retained its antimicrobial effectiveness for millions of years with no frequent emergence of resistant strains. First,

Role of the cell-wall structure in the retention of bacteria by microfiltration membranes [PDF]
, 2009 This experimental study investigates the retention of bacteria by porous membranes. The transfer of bacteria larger than the nominal pore size of microfiltration track-etched membranes has been studied for several kinds of bacterial strains.

mBio, 2015 Most bacterial cells are enclosed in a single macromolecule of the cell wall polymer, peptidoglycan, which is required for shape determination and maintenance of viability, while peptidoglycan biosynthesis is an important antibiotic target.
