wall teichoic acidThe chapter about the Gram-positive bacterial cell wall gives a brief historical background on the discovery of Gram-positive cell walls and their constituents and microscopic methods applied for studying the Gram-positive cell envelope. Followed by the description of the different ...
Peptidoglycan is a single macromolecule made of glycan chains crosslinked by peptide side branches that surrounds the cell, acting as a constraint to internal turgor. In Gram-positive bacteria, peptidoglycan is tens of nanometres thick, generally portrayed as a homogeneous structure that provides ...

TEICHOIC acids are strongly acidic polymers containing phosphate, which are present in all Gram-positive bacteria1. They are found at two distinct locations in the cell envelope: associated with a glycolipid on the outer surface of the cytoplasmic membra
Furthermore, mutations affecting Lpp function substantially increase bacterial susceptibility to the antibiotic vancomycin, indicating that Lpp-dependent effects can affect antibacterial drug efficacy.Similar content being viewed by others The architecture of the Gram-positive bacterial cell wall Article 29 ...

A variety of strains of the genus Lactobacillus was investigated with respect to the structure, softness, and interactions of their outer surface layers in order to construct structure-property relations of the Gram-positive bacterial cell wall. The role of the conformational properties of the constit...
1A). Peptidoglycan, a major component of the Gram-positive bacterial cell wall, is responsible for this reaction, because purified peptidoglycan from S. aureus also induced muscle contraction (Fig. 1B). In addition, glucan from S. cerevisiae induced muscle contraction (Fig. 1C). We previously...
In this study the cell wall charge density of Gram-positive bacterial strains, including four coryneforms and a Bacillus brevis, is assessed by proton titrations of whole bacterial cells and isolated cell walls at different electrolyte concentrations. At neutral pH rather high values, between 0.5 ...
Peptidoglycans are constituents of bacterial cell walls. Peptidoglycan is present in most of the Gram-positive bacteria and some of the Gram-negative bacterial. It exhibited various biological activities in the host, especially in immunomodulating. This article summarized the structure, isolation and pur...
