Peptidoglycan structure and architecture.
In several species examined, the fine structure of the peptidoglycan significantly varies with the growth conditions, and the different models for the architecture are discussed with respect to structural and physical parameters.
Bacterial peptidoglycan (murein) hydrolases.
The current view on the regulation of autolysins and on the role of cytoplasm hydrolases in peptidoglycan recycling and induction of beta-lactamase is reviewed.
From the regulation of peptidoglycan synthesis to bacterial growth and morphology
This Review discusses how growth of the sacculus is sensitive to mechanical force and nutritional status, and describes the roles of peptidoglycan hydrolases in generating cell shape and of D-amino acids in sacculus remodelling.
Type VI secretion delivers bacteriolytic effectors to target cells
It is shown that the type VI secretion system of Pseudomonas aeruginosa breaches this barrier to deliver two effector proteins, Tse1 and Tse3, to the periplasm of recipient cells, indicating a mechanism for export whereby effectors do not access donor cellperiplasm in transit.

This review describes the structure of secondary modifications and of attachment sites of surface polymers in the glycan strands of peptidoglycan and provides an overview of the occurrence of these modifications in various bacterial species.
Regulation of peptidoglycan synthesis by outer membrane proteins
It is demonstrated that PG synthases are also controlled from outside the sacculus, and the data suggest that the LpoB-PBP1B complex contributes to OM constriction during cell division.
Why are pathogenic staphylococci so lysozyme resistant? The peptidoglycan O‐acetyltransferase OatA is the major determinant for lysozyme resistance of Staphylococcus aureus
It is shown that OatA, an integral membrane protein, is the molecular basis for the high lysozyme resistance in staphylococci.
Murein (peptidoglycan) structure, architecture and biosynthesis in Escherichia coli.
A model in which morphogenesis of the rod-shaped E. coli is driven by cytoskeleton elements competing for the control over the murein synthesis multi-enzyme complexes is presented.
The tubulin homologue FtsZ contributes to cell elongation by guiding cell wall precursor synthesis in Caulobacter crescentus
It is shown that in Caulobacter crescentus, FtsZ also plays a major role in cell elongation by spatially regulating the location of MurG, which produces the essential lipid II peptidoglycan cell wall precursor.
A widespread family of bacterial cell wall assembly proteins
The widespread LytR–Cps2A–Psr (LCP) protein family, of previously unknown function, is identified as novel enzymes required for AP synthesis, suggesting that they carry out the final step of transferring APs from their lipid‐linked precursor to cell wall peptidoglycan (PG).
