CELL WALL OF ARCHAEA · The cell wall is present in most archaea except Thermoplasma and Ferroplasma . · The cell wall of Archaea is surrounding the cell outside the cytoplasmic membrane and is mediating the interaction with the environment. · Archaeal cell wall can be involved in Cell shape maintenance, Protection against Virus, Heat, Acidity or Alkalinity. · Archaea do not have Peptidoglycan but have Pseudomurein and different in its composition to Murein. · Archaea have Pseudopeptidoglycan and it is similar to bacterial peptidoglycan (morphologically, functionally) but is chemically distinct. · In Archaea, instead of NAM, it contains N-Acetyltalosamine Uronic Acid (NAT) linked to NAG, with peptide interbridges to increase strength. · In some Archaea, the C...
