The hydrolase LpqI primes mycobacterial peptidoglycan recycling [PDF]
Bacterial growth and division require remodelling of the cell wall, which generates free peptidoglycan fragments. Here, Moynihan et al. show that Mycobacterium tuberculosis can recycle components of their peptidoglycan, and characterise a crucial enzyme ...

Bacterial peptidoglycan (murein) hydrolases [PDF]
Most bacteria have multiple peptidoglycan hydrolases capable of cleaving covalent bonds in peptidoglycan sacculi or its fragments. An overview of the different classes of peptidoglycan hydrolases and their cleavage sites is provided. The physiological functions of these enzymes include the regulation of cell wall growth, the turnover of peptidoglycan ...

Protein complexes and proteolytic activation of the cell wall hydrolase RipA regulate septal resolution in mycobacteria. [PDF]
Peptidoglycan hydrolases are a double-edged sword. They are required for normal cell division, but when dysregulated can become autolysins lethal to bacteria.

Structure-based inhibitor design for reshaping bacterial morphology
Peptidoglycan hydrolase 3 (Pgp3) inhibitors are designed that can change the helical morphology of Campylobacter jejuni to rod-shaped and decrease its virulence.

A holin/peptidoglycan hydrolase‐dependent protein secretion system [PDF]
AbstractGram‐negative bacteria have evolved numerous pathways to secrete proteins across their complex cell envelopes. Here, we describe a protein secretion system that uses a holin membrane protein in tandem with a cell wall‐editing enzyme to mediate the secretion of substrate proteins from the periplasm to the cell exterior.

Two New M23 Peptidoglycan Hydrolases With Distinct Net Charge [PDF]
Bacterial peptidoglycan hydrolases play an essential role in cell wall metabolism during bacterial growth, division, and elongation (autolysins) or in the elimination of closely related species from the same ecological niche (bacteriocins). Most studies concerning the peptidoglycan hydrolases present in Gram-positive bacteria have focused on clinically

Asymmetric peptidoglycan editing generates cell curvature in Bdellovibrio predatory bacteria
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]
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
