Pseudopeptidoglycan (also known as pseudomurein) is a major cell wall component of some archaebacteria that chemically differs from but morphologically, functionally, and structurally resembles eubacterial peptidoglycan. The basic components are N-acetylglucosamine and N-acetyltalosaminuronacid (Peptidoglycan has N-acetylmuraninacid instead) which are linked by a β-1,3-glycosidic bond.
