Peptidoglycan is a polymer comprised of amino acids and sugars with a backbone made of alternating N-acetylglucosamine and N-acetylmuramic acid residues (MurNAc). From:Archives of Biochemistry and Biophysics,2019 About this page Add to MendeleySet alert ...
S. aureus PG belongs to group A3 (i.e., crosslinking between stem peptides is made up of interpeptide bridges consisting of monocarboxylic l-amino acids or glycine or both). PG of the A3 group is very common among Gram-positive bacteria (Schleifer and Kandler, 1972). B. subtilis PG ...
Peptidoglycan is made up of circumferentially oriented bands of material interspersed with a more porous network. Super-resolution fluorescence microscopy reveals an unexpected discontinuous, patchy synthesis pattern. We present a consolidated model of growth via architecture-regulated insertion, where we ...
The peptidoglycan is a heteropolymer composed of polysaccharide chains which are cross-linked through short peptides. The polysaccharide moiety (glycan) is made up of beta-1,4 glycosidically linked N-acetylglucosamine and N-acylmuramic acid residues. The carboxyl group of muramic acid is usually ...
Cell wall structural dynamics allowing growth and division, while maintaining integrity is a basic problem governing the life of bacteria. The polymer peptidoglycan is the main structural component for most bacteria and is made up of glycan strands that are cross-linked by peptide side chains. ...
Fig. 2: The peptidoglycan hydrolytic ability is required and sufficient for LPH’s colitis protective effects. aSchematic of LPH’s sequence organization: yellow represents the signal sequence; blue represents the conserved 3D-domain. The predicted active site residues are typed in red.bA summarizat...
The main source of energy and nutrients for deep-sea biota is the sedimentation of POM from the surface seawater [1,4]. The depolymerization of biopolymers by EEs is considered the pivotal and rate-limiting step in the OM cycling process [5]. To uncover the active microbes involved in biopo...

3A). The large lobe is made up of a short 310 helix, α1-α2 and α4-α6, whereas the small lobe consists of α3 and a β-hairpin formed by β1-β2. The termini are covalently linked by a Cys32-Cys177 disulfide bond, which connects the N-terminal 310 helix to the C-...
1. A composition for detecting a peptidoglycan comprising extract of insect body fluid which has a phenoloxidase activity on the peptidoglycan without the addition of calcium. 2. The composition according to claim 1, wherein the extract of insect body fluid is a plasma solution separated from inse...
