Membrane-partitioned cell wall synthesis in mycobacteria
Many antibiotics target the assembly of cell wall peptidoglycan, an essential, heteropolymeric mesh that encases most bacteria. In rod-shaped bacteria, cell wall elongation is spatially precise yet relies on limited pools of lipid-linked precursors that ...

Peptidoglycan- and Lipoteichoic Acid-induced Cell Activation Is Mediated by Toll-like Receptor 2*
The life-threatening complications of sepsis in humans are elicited by infection with Gram-negative as well as Gram-positive bacteria. Recently, lipopolysaccharide (LPS), a major biologically active agent of Gram-negative bacteria, was shown to mediate ...

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.

The peptidoglycan layer is responsible for maintaining bacterial cell shape and permitting cell division. Cell wall growth is facilitated by peptidoglycan synthases and hydrolases and is potentially modulated by components of the central carbon ...

A lysozyme-like protein in Brucella abortus is involved in the early stages of intracellular replication [PDF]
Secretion of proteins in Gram-negative bacteria is a high-energy consuming process that requires the translocation across two membranes and a periplasmic space composed of a mesh like layer, the peptidoglycan.

Cell wall peptidoglycan in Mycobacterium tuberculosis: An Achilles’ heel for the TB-causing pathogen
Tuberculosis (TB), caused by the intracellular pathogen Mycobacterium tuberculosis, remains one of the leading causes of mortality across the world. There is an urgent requirement to build a robust arsenal of effective antimicrobials, targeting novel ...

Resistance of O-acetylated gonococcal peptidoglycan to human peptidoglycan-degrading enzymes [PDF]
Two naturally occurring forms of gonococcal peptidoglycan (PG) were tested for their susceptibility to human PG hydrolases. Purified 3H-labeled PG substituted extensively with O-acetyl derivatives (O-PG; from Neisseria gonorrhoeae FA19) and 14C-labeled O-acetyl-deficient PG (non-O-PG; from N. gonorrhoeae RD5) were mixed together and treated with either

Borrelia burgdorferi peptidoglycan is a persistent antigen in patients with Lyme arthritis
Significance Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most common vector-borne disease in North America. If early infection is untreated, it can result in late-stage manifestations, including arthritis. Although antibiotics are

Uptake, recognition and responses to peptidoglycan in the mammalian host
Microbiota, and the plethora of signalling molecules that they generate, are a major driving force that underlies a striking range of inter-individual physioanatomic and behavioural consequences for the host organism.
