A polymer that contains equal amounts of peptide and polysaccharide.
Polysaccharide backbone with peptide cross-links that covers surface of cytoplasmic membrane and gives bacteria their shape (Lecture: The Bacterial Cell: Structure, Function, Growth, and Gene Regulation I, 1/24/02)
the cell wall material of Eubacteria, a/k/a murein. The structure of murein is discussed here.
The cell wall material of many prokaryotes, consisting of a single enormous molecule that surrounds the entire cell.
Large polymer that provides much of the strength and rigidity of bacterial cell walls.
carbohydrate polymer cross-linked by proteins. It is found in the cell wall of Gram positive bacteria, where it stains with the dye crystal-violet.
Peptidoglycan, also known as murein, is a polymer consisting of sugars and amino acids that forms a homogeneous layer outside the plasma membrane of eubacteria. Some Archaea have a similar layer of pseudopeptidoglycan. Peptidoglycan serves a structural role in the bacterial cell wall, giving the wall shape and structural strength, as well as counteracting the osmotic pressure of the cytoplasm.
