A competitive radioimmunoassay for peptidoglycan monomer

Clinica Chimica Acta, 1991
The preparation and characterization of the essential components to be used in the radioimmunoassay of peptidoglycan monomer (PGM) is described. In order to raise the anti-peptidoglycan monomer antibodies 14C-labelled peptidoglycan monomer-bovine serum albumin conjugate was prepared by the coupling of 14C-peptidoglycan monomer to bovine serum albumin ...

The role of peptidoglycan in pathogenesis

Current Opinion in Microbiology, 2005
Bacterial pathogens rely on a variety of virulence factors to establish the colonization of a new niche. Although peptidoglycan and its muropeptide derivatives have been known to possess potent biological properties, until recently the molecular bases were poorly understood.

Peptidoglycan

2015
Peptidoglycan is an essential component of the bacterial cell envelope and protects the cell from bursting due to turgor and maintains cell shape. Composed of glycan chains connected by short peptides, peptidoglycan forms a net-like macromolecule around the cytoplasmic membrane.

Peptidoglycan in eukaryotes: Unanswered questions

Phytochemistry, 2020
Peptidoglycan has been retained in chloroplasts that have evolved from cyanobacteria along some evolutionary tracks, but has seemingly been quickly eliminated during evolution of others. It has been eliminated in Rhodophyta, Chlorophyta, Pteridophyta and Spermatophyta, but has been retained in streptophyte algae, Glaukophyta, and Lycophyta.

Peptidoglycane bei Pyelonephritis [PDF]

, 1977
Bei einem Teil der Patienten mit chronischer Pyelonephritis lassen sich im Harn keine vermehrten Bakterienzahlen nachweisen. Auch das Nierengewebe selbst ist bakteriologisch negativ. Trotzdem schreitet der destruierende Entzundungsprozes im Nierenparenchym fort.

Detection of peptidoglycans by NOD proteins

Trends in Cell Biology, 2003
Mechanisms of innate immune defense are based on the recognition of invariant microbial molecular patterns by specific receptors, followed by the activation of signaling pathways and the expression of effector molecules that will defeat the invading microorganism.

Peptidoglycan Structure

2011
Information on the peptidoglycan structure is an indispensable component for the description of new genera of Gram-positive bacteria. In certain genera, structural variations of the peptidoglycan support even the differentiation at the species level. The analysis of the peptidoglycan requires the isolation and purification of this three-dimensionally ...

Biological properties of bacterial peptidoglycan

APMIS, 1993
Synthetic and natural muramyl peptides have a variety of biological actions in mammals, including the abilities to enhance sleep and body temperature. Although muramyl peptides can be detected constitutively in mammalian organisms, no biochemical synthetic pathways are known for muramyl peptides in mammals.

Measure of Peptidoglycan Hydrolase Activity

2017
Most gene clusters encoding multiprotein complexes of the bacterial cell envelope, such as conjugation and secretion systems, Type IV pili, and flagella, bear a gene encoding an enzyme with peptidoglycan hydrolase activity. These enzymes are usually glycoside hydrolases that cleave the glycan chains of the peptidoglycan.
