Summary Introduction
Archaeal cells varies in size ranging from 0.2 µm to >700 µm in diameter. Cell wall and cytoplasmic membrane are considered as the most vital structures of a cell. The wide range of cell wall structures, including wall made up of proteins, glycoproteins, polysaccharides is seen in Archaea. In the cell wall of some methanogens (Archaea), a polysaccharide molecule similar to peptidoglycan called pseudomurein is present. Pseudomurein consists of alternating repeats of N-acetyltaloaminuronic acid and N-acetylglucosamine.
