The differential binding of crystal violet to this layer is used to distinguish between gram positive and gram negative bacteria in Gram's stain.
Autolysins effect the breakdown of this substance, and bactoprenol transfers its monomers. Pentaglycine structures crosslink alanine-glutamine-lysine-alanine chains in this substance. It is composed of alternating N-acetylglucosamine and N-acetylmuramic acid residues, and those tetrapeptide chains have unusual stereochemistry. Its beta-(1,4)-glycosidic bonds are hydrolyzed by lysozyme. The differential binding of crystal violet to this layer is used to distinguish between gram positive and gram negative bacteria in Gram's stain. For 10 points, identify this substance found in bacterial cell walls, which contains both sugar residues and amino acids.
