Archea have three RNA polymerases like eukaryotes, butbacteria have only one. ... Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). Can archaea cause disease?
英文: Archaean cell walls lack murein, a common component of bacterial cell walls, and their lipids have ether links rather than ester links. 中文: 古细菌的细胞壁缺乏细菌细胞壁组成的普遍物质-胞壁质,其连接是醚连接而不是酯连接。更详细... ...
archaea (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, ...
Cell walls can be as simple as a proteinaceous surface layer or as complicated as in some methanogens with multiple layers, additional sheaths enclosing several cells and even more complex cell wall compounds. Archaea exhibit a broad variety in cell appendages that are different from bacterial ones...

Archaea possess a broader range of cell envelope structural formats than eubacteria and their cell walls do not contain peptidoglycan. Some archaea have only a single S-layer as their cell wall (e.g. Methanococcus jannaschii and Sulfolobus acidocaldarius), whereas others have multiple layers (e...
1.Cell walls: virtually all bacteria contain peptidoglycan in their cell walls; however, archaea and eukaryotes lack peptidoglycan. Various types of cell walls exist in the archaea. Therefore, the absence or presence of peptidoglycan is a distinguishing feature between the archaea and bacteria. ...
