Sentences with word «peptidoglycan»

Or try «penicillin», which, we are told, «exerts a bacteriostatic and bactericidal effect by interfering with the synthesis of peptidoglycan».

Her final year research project was the study of bactieral cell wall peptidoglycan structure by atomic force microscopy.

This work zeroes in on trying to stop construction of a bacterial cell layer called peptidoglycan, a mesh - like structure that, in gram - negative bacteria like E. coli, rests between the inner and outer cell membranes.

Animal experiments Cytosolic and secreted peptidoglycan - degrading enzymes in Drosophila respectively control local and systemic immune responses to microbiota — Bernard Charroux — Cell Host & Microbe

Miklossy J. Chronic inflammation and amyloidogenesis in Alzheimer's disease: Putative role of bacterial peptidoglycan, a potent inflammatory and amyloidogenic factor.

Lysozyme breaks down peptidoglycans found in bacterial cell walls especially those of Gram - positive bacteria.

In particular, the Silver Institute, in a paper entitiled «Silver, The Healthful Metal», notes that this deactivation of bacteria occurs by silver ions reacting with exposed peptidoglycans.

Mammalian cells do not contain peptidoglycans, which explains the selective action of silver; ionic silver is not disease specific but cell - structure specific.

More specifically, it prevents the final inclusion of a variety of peptides into peptidoglycan molecules.

Why not say that penicillin «impairs synthesis of cell wall peptidoglycan, stopping bacteria from growing and killing them»?

These drugs work by targeting essential components of a bacterium's cell wall called peptidoglycans.

The Toll - dependent defense against Gram - positive bacterial infections in Drosophila is mediated through the peptidoglycan recognition protein SA (PGRP - SA).

In this case «bacteriostatic», but not «bactericidal», is defined on another page, and we have to look elsewhere to discover that peptidoglycan is part of the cell wall.

The proteins were known to contribute to construction of the peptidoglycan, but their specific function was never demonstrated.

The researchers used a toxin some cells release that is known to «eat» the flipped lipid shortly after it appears on the outside of its inner membrane, effectively halting construction of the peptidoglycan.

But one detail has remained elusive: which protein could get a specific lipid required for building the peptidoglycan layer to change its location, from the inside of the inner membrane to the outside of that membrane, where the peptidoglycan construction is under way.

Ruiz and colleagues have previously shown that MurJ has several features that point to this possibility: A model of its structure shows the characteristic cavity that a flippase needs to have; eliminating the protein showed that cells wouldn't make the peptidoglycan layer; and it was demonstrated to be related to other flipping proteins.

Royet will present his latest data dissecting the cellular and molecular mechanisms by which one single microbiota - derived compound, peptidoglycan, influences the behavior, the physiology, and the homeostasis of its infected host.

These materials includes components of the bacterial cell wall, like lipopolysaccharides, peptidoglycans and proteins, and the metabolic by - products mentioned above.

This class is bactericidal and acts by inhibiting the synthesis of the peptidoglycan layer of the bacterial cell wall through binding to the penicillin binding protein (PBP)[5].

No peptidoglycan, no bacterial cell wall.
