Peptidoglycan in a sentence

Inhibition of cross-linkage by β-lactams causes a build-up of peptidoglycan precursors, which triggers the digestion of existing peptidoglycan by autolytic hydrolases without the production of new peptidoglycan.

A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed.

Antibiotics such as penicillin commonly target bacterial cell wall formation (of which peptidoglycan is an important component) because animal cells do not have cell walls.

Bacteria constantly remodel their peptidoglycan cell walls, simultaneously building and breaking down portions of the cell wall as they grow and divide.

Bdellovibrio attacks other gram-negative bacteria by attaching itself to the prey cell's outer membrane and peptidoglycan layer, after which it creates a small hole in the outer membrane.

Chloroplastidan chloroplasts have lost the peptidoglycan wall between their double membrane, and have replaced it with an intermembrane space.

Despite their thicker peptidoglycan layer, gram-positive bacteria are more receptive to antibiotics than gram-negative, due to the absence of the outer membrane.

Glaucophytes have chloroplasts that retain a peptidoglycan wall between their double membranes, like their cyanobacterial parent.

Gram-negative bacteria main Gram-negative bacteria generally possess a thin layer of peptidoglycan between two membranes (diderms).

In addition, the build-up of peptidoglycan precursors triggers the activation of bacterial cell wall hydrolases and autolysins, which further digest the cell wall's peptidoglycans.

In contrast to gram-positive bacteria, all archetypical gram-negative bacteria are bounded by a cytoplasmic membrane and an outer cell membrane; they contain only a thin layer of peptidoglycan (2–3 nm) between these membranes.

In contrast to gram-positive bacteria, all archetypical gram-negative bacteria have a cytoplasmic membrane as well as an outer cell membrane, and contain only a thin layer of peptidoglycan (2–3 nm) between the membranes.

In cultures of Bacillus, Butyrivibrio, and Clostridium, a decrease in peptidoglycan thickness during growth coincides with an increase in the number of cells that stain gram-negative.

In gram-positive bacteria, the S-layer is attached to the peptidoglycan layer (in gram-negative bacteria, the S-layer is attached directly to the outer membrane ).

In that group, the peptidoglycan is a modified form very different from the kind found in bacteria.

New phages were released by burst of the infected cell after lysis of host membranes by a peptidoglycan hydrolase.

Penicillin-binding proteins form the bonds between oligopeptide crosslinks in peptidoglycan.

Peptidoglycan forms around 90% of the dry weight of Gram-positive bacteria but only 10% of Gram-negative strains.

The cell wall consists of peptidoglycan in bacteria, and acts as an additional barrier against exterior forces.

The dipicolinic acid helps stabilize the proteins and DNA in the endospore. citation : 141 Next the peptidoglycan cortex forms between the two layers and the bacterium adds a spore coat to the outside of the forespore.
