Abstract. The distribution of the various cell wall and cell envelope (S-layer) polymers among the main lineages of the domain Archaea (Archaebacteria) and the chemical composition and primary structure of polymers forming rigid cell wall sacculi is described. Differences between bacteria and archaea in their sensitivity to antibiotics which inhibit cell wall synthesis in bacteria are discussed. 
The Cell Envelopes of Haloarchaea: Staying in Shape in a World of Salt
TLDR
The haloarchaea possess various cell envelope types, composed of different polymers such as S-layers, heteropolysaccharides, or glutaminylglucans, which are described below. Expand
Cell Structure, Organization, Bacteria and Archaea
TLDR
This contribution deals with the ultrastructure of prokaryotes and the architecture of bacteria and archaea is treated through the use of cryo-electron tomography. Expand
Archaeal Cell Walls
TLDR
Next to the bacterial and eukaryal domains, Archaea form the third domain of life and one major difference to bacteria is the composition of the cell wall, which is composed of glycan polymers, like glutaminylglycan, heterosaccharide, methanochondroitin or pseudomurein. Expand
The Cell Walls that Bind the Tree of Life
TLDR
It is indicated that the machinery responsible for synthesizing the cell walls of land plants, of their nearest algal relatives, and of some very ancient algal lineages can be traced back to ancient primary endosymbiotic events involving Eubacteria. Expand
Mechanism of osmoprotection by archaeal S-layers: a theoretical study.
TLDR
The theoretical analysis of a model S-layer-membrane assembly, derived from the typical cell envelope of Crenarchaeota, explains how S-layers impart lipid membranes with increased resistance to internal osmotic pressure and offers a quantitative assessment of S- layer stability. Expand
Archaeal Cell Walls.
The cell wall of archaea, as of any other prokaryote, is surrounding the cell outside the cytoplasmic membrane and is mediating the interaction with the environment. In this regard, it can beExpand
The molecular basis of salt adaptation in Methanosarcina mazei Gö1
TLDR
This article will review discoveries made within the last years that will culminate in the description of the overall cellular response of M. mazei Gö1 to elevated salinities. Expand
S-layer and cytoplasmic membrane – exceptions from the typical archaeal cell wall with a focus on double membranes
  • A. Klingl

TLDR
The common idea of typical cell wall architecture in archaea consists of a pseudo-crystalline proteinaceous surface layer (S-layer), situated upon the cytoplasmic membrane, but within the crenarchaea, the S-layer often represents the only cell wall component, but there are various exceptions from this wall architecture. Expand
Pili and flagella biology, structure, and biotechnological applications.
TLDR
The documented and potential technological exploitation of bacterial surface filaments in light of their structural and functional traits are reviewed. Expand
Evolution of the Archaea.
TLDR
Recently, many new groups of Archaea that have not yet been cultured have been detected by PCR amplification of 16S ribosomal RNA from environmental samples, and the phenotypic and genotypic characterization of these new groups is now a top priority for further studies on archaeal evolution. Expand

Pathways and Principles of the Biosynthesis of Methanobacterial Cell Wall Polymers
TLDR
This work has investigated the biosynthesis of three different methanobacterial cell wall polymers: a peptidoglycan (pseudomurein), a heteropolysaccharide (methanochondroitin) and a glycoprotein (S-layer). Expand
Nucleotide-activated oligosaccharides are intermediates of the cell wall polysaccharide of Methanosarcina barkeri.
TLDR
From cell extracts of Methanosarcina barkeri four uridine diphosphate and one undecaprenyl pyrophosphate-activated intermediate(s) of the methanochondroitin were isolated, in contrast to the known biosynthetic pathways of polysaccharides from other prokaryotes and eukaryotes, nucleotide activated oligosaccharide precursors are involved.

Chapter 8 Cell envelopes of archaea: Structure and chemistry
Publisher Summary Cell envelopes of archaea differ distinctly from those of bacteria and show remarkable structural and chemical diversity. Murein, the typical sacculus-forming polymer of bacteria,Expand
Chemical structure of the cell wall polymer of methanosarcina
TLDR
This unique polymer of Methanosarcina is another example of the various eucaryotic resemblances found in archaebacteria and may be termed “methanochondroitin”. Expand
The cell wall polymer of the extremely halophilic archaeon Natronococcus occultus.
TLDR
The cell wall polymer of Natronococcus occultus, which represents a novel type of natural glycoconjugate, has a relative molecular mass of 54 kDa and the analysis of additional fragments indicated the presence of two different oligosaccharides linked to the poly-(gamma-glutamine) chain of the intact polymer.

Summary The chemical composition of trypsin-treated cell walls of three strains of Halococcus morrhuae was determined. Neutral sugars (glucose, mannose, galactose), uronic acids (glucuronic andExpand
The sensitivity of archaebacteria to antibiotics
TLDR
It is pointed out that the very characteristic sensitivity pattern of archaebacteria may serve as a guideline in the search for further biochemical and molecular differences between archaEBacteria, eubacteria, and eucaryotes, and that it may also be helpful in designing selective media for the enrichment and isolation of new types of archAebacteria.

Biosynthesis of pseudomurein: isolation of putative precursors from Methanobacterium thermoautotrophicum.
TLDR
In aqueous trichloroacetic acid extracts of Methanobacterium thermoautotrophicum the findings indicate that the biosynthetic pathways of murein and pseudomurein are quite different. Expand
Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.
TLDR
It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms. Expand
