Pseudopeptidoglycan - wikipedia Pseudopeptidoglycan Pseudopeptidoglycan ( also known as pseudomurein ) is a major cell wall component of some Archaea that differs from bacterial peptidoglycan in chemical structure, but resembles bacterial peptidoglycan in function and physical structure. The basic components are N - acetylglucosamine and N - acetyltalosaminuronic acid ( peptidoglycan has N - acetylmuramic acid instead ), which are linked by β - 1, 3 - glycosidic bonds. Lysozyme, a host defense mechanism present in human secretions ( e.g. saliva and tears ), is ineffective against organisms with pseudopeptidoglycan cell walls. Lysozyme can break β - 1, 4 - glycosidic bonds to degrade peptidoglycan ; however, pseudopeptidoglycan has β - 1, 3 - glycosidic bonds, rendering lysozyme useless. Pseudomurein can be degraded by pseudomurein endoisopeptidase found in two prophages.
