Archaeal Cell Walls

Archaea represent the third domain of life with the Bacteria and Eukarya. They have developed different types of cell envelopes.

Keywords: glutaminylglycan; heteropolysaccharide; methanochondroitin; pseudomurein; S-layer (glyco-)protein; Archaea; cell envelope

Figure 1. CM, cytoplasmic or plasma membrane; GC, glycocalyx; HP, heteropolysaccharide sacculus; MC, methanochondroitin matrix; PM, pseudomurein sacculus; PS, proteinaceous sheath; SL, S-layer.
Figure 2. Chemical structure of the pseudomurein.
Figure 3. Proposal for the biosynthesis of the pseudomurein.

I. Cytoplasmic stage: formation of the UDP-activated disaccharide and the UDP-activated pentapeptide intermediates. II. Cytoplasmic stage: formation of the UDP-activated disaccharide pentapeptide. III. Lipid stage: formation of undecaprenyl pyrophosphate (UdP-PP) pentapeptide and tetrapeptide intermediates. During transpeptidation one C-terminal alanine residue is split off.
