We have confidence to be your essential research assistant in the field of glycobiology.

Background

Peptidoglycan (PG, also known as murein) exists in the cell walls of gram-positive bacteria and gram-negative bacteria in eubacteria. The backbone of peptidoglycan is a polysaccharide chain formed by two sugar derivatives: N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) that alternately connected by β-1,4-glycosidic bonds. Two parallel sugar chains are connected laterally to form a network of peptidoglycan. PG is essential for maintaining cell integrity because of its ability to withstand turgor pressure. Any external force that affects its biosynthesis or degradation will interfere with cell viability. Therefore, PG is one of the main targets of antibacterial drugs. The study of peptidoglycan structure also plays a vital role in understanding the immune response, phage susceptibility and serological behavior, as well as the classification and identification of bacteria. Although the structure and architecture of PG have been studied for a long time, its detailed 3D structure is still an open question.
