Document Summary
Some archaeal cell walls do not contain pseudomurein, instead they have other polysaccharide polymers and/or an s-layer protein that can form paracrystalline structures that have gaps that allow for molecule movement. S-layers are most common cell wall type in archaea. s-layer is the outermost of cell. it is a. Also found in domain bacteria protein in glycoprotein. Always outermost layer: s-layer only cytoplasmic membrane is monolayer. growth conditions are very hot for this, s-layer and pseudomurein. cm is bilayer. domain bacteria have s-layer as well. Some bacteria and archaea have extra outer shell surrounding the cell, made of one type of protein that forms a paracrystalline structure. structure. Instead they have tough cm contain sterols for strength and rigidity. they live in animal host cells, and no not need cell wall to protect it. Myco - small, plasma = cm, thermo = grow in hot areas / archaea.
