what is the composition of the cell wall of archaebacteria

Cell wall of archaebacteria is different from eubacteria in composition. It does not contain peptidoglycan. Rather, archaebacteria such as methanobacteria contain pseudopeptidoglycan or pseudomurein which is different from peptidoglycan due to the absence of D-amino acids and N-Acetyl muramic acid.

  • Archaea are single-celled microorganisms that lack a cell nucleus and membrane-bound organelles.

  • Like other living organisms, archaea have a semi-rigid cell wall that protects them from the environment.

  • The cell wall of archaea is composed of S-layers and lack peptidoglycan molecules with the exception of methanobacteria who have pseudopeptidoglycan in their cell wall.
