The bacterial cell wall is composed of a cross-linked heteropolymer matrix called peptidoglycan and determines cell shape and protects the cell from osmotic lysis. Interestingly the peptidoglycan sacculus that surrounds the cells is continuously remodeled throughout the bacteria's cell cycle. For instance, when the cells divide, extracellular peptidoglycan hydrolases are required to cleave covalent bonds within the peptidoglycan sacculus to permit ...

Solution Summary

Peptidoglycan is a very rigid sugar-coated protein matrix that makes up the cell wall of many bacteria. If peptidoglycan is so rigid how do cells divide? Allow me to introduce the peptidoglycan recycling pathway.
