The Role of Mre Factors and Cell Division in Peptidoglycan Growth in the Multicellular Cyanobacterium Anabaena

mBio, 2022
Bacteria in general serve two main tasks: cell growth and division. Both processes include peptidoglycan extension to allow cell expansion and to form the poles of the daughter cells, respectively.

An NlpC/P60 protein catalyzes a key step in peptidoglycan recycling at the intersection of energy recovery, cell division and immune evasion in the intracellular pathogen Chlamydia trachomatis.

PLoS Pathogens, 2023
The obligate intracellular Chlamydiaceae do not need to resist osmotic challenges and thus lost their cell wall in the course of evolution. Nevertheless, these pathogens maintain a rudimentary peptidoglycan machinery for cell division.

Acinetobacter baumannii Can Survive with an Outer Membrane Lacking Lipooligosaccharide Due to Structural Support from Elongasome Peptidoglycan Synthesis

mBio, 2021
Gram-negative bacteria resist external stresses due to cell envelope rigidity, which is provided by two membranes and a peptidoglycan layer. The outer membrane (OM) surface contains lipopolysaccharide (LPS; contains O-antigen) or lipooligosaccharide (LOS)

Recent Advances in Peptidoglycan Synthesis and Regulation in Bacteria

Biomolecules, 2023
Bacteria must synthesize their cell wall and membrane during their cell cycle, with peptidoglycan being the primary component of the cell wall in most bacteria.

Specificity determinants for lysine incorporation in staphylococcus aureus peptidoglycan as revealed by the structure of a MurE enzyme ternary complex [PDF]

, 2013
Background: MurE controls stereo chemical incorporation of Lysine or diaminopimelate into peptidoglycan stem peptides Results: The structure of S.aureus MurE reveals an unexpected lack of specificity for Lysine within the active site.

A SpoIID Homolog Cleaves Glycan Strands at the Chlamydial Division Septum

mBio, 2019
Chlamydiales species are obligate intracellular bacteria lacking a classical peptidoglycan sacculus but relying on peptidoglycan synthesis for cytokinesis.

Amidation of glutamate residues in mycobacterial peptidoglycan is essential for cell wall cross-linking

Frontiers in Cellular and Infection Microbiology, 2023
IntroductionMycobacteria assemble a complex cell wall with cross-linked peptidoglycan (PG) which plays an essential role in maintenance of cell wall integrity and tolerance to osmotic pressure.

Atomic Force Microscopy of Side Wall and Septa Peptidoglycan From Bacillus subtilis Reveals an Architectural Remodeling During Growth

Frontiers in Microbiology, 2018
Peptidoglycan is the fundamental structural constituent of the bacterial cell wall. Despite many years of research, the architecture of peptidoglycan is still largely elusive.
