A Study of the Cell Envelope of the Halobacteria [PDF]
SUMMARY: Electron microscopy on thin sections of three different extremely halophilic Halobacterium species showed that their cell envelopes were of similar general construction: an inner membrane and an outer layer. The outer layer stains most strongly in the outermost part.

Shaping the Archaeal Cell Envelope [PDF]
Although archaea have a similar cellular organization as other prokaryotes, the lipid composition of their membranes and their cell surface is unique. Here we discuss recent developments in our understanding of the archaeal protein secretion mechanisms, the assembly of macromolecular cell surface structures, and the release of S-layer-coated vesicles ...

Bacterial cell-envelope glycoconjugates [PDF]
Prokaryotic glycosylation fulfills an important role in maintaining and protecting the structural integrity and function of the bacterial cell wall, as well as serving as a flexible adaption mechanism to evade environmental and host-induced pressure.

The bacterial cell envelope is a key subcellular compartment with important roles in antibiotic resistance, nutrient acquisition, and cell morphology. We seek to gain a better understanding of proteins that contribute to the function of the cell envelope

Peptidoglycan Remodeling Enables
Gram-negative bacteria have a tripartite cell envelope with the cytoplasmic membrane (CM), a stress-bearing peptidoglycan (PG) layer, and the asymmetric outer membrane (OM) containing lipopolysaccharide (LPS) in the outer leaflet.

Gram-negative bacteria resist external stresses due to cell envelope rigidity, which is provided by two membranes and a peptidoglycan layer. The outer membrane (OM) surface contains lipopolysaccharide (LPS; contains O-antigen) or lipooligosaccharide (LOS)

The Cell Envelope Structure of Cable Bacteria [PDF]
Cable bacteria are long, multicellular micro-organisms that are capable of transporting electrons from cell to cell along the longitudinal axis of their centimeter-long filaments. The conductive structures that mediate this long-distance electron transport are thought to be located in the cell envelope.

The Virus Envelope in Cell Attachment
The mechanism of penetration and uncoating of enveloped animal viruses has recently been the subject of renewed controversy. Electron microscopic studies have led a number of investigators to conclude that penetration takes place by cellular engulfment (viropexis) of intact virus particles (Dales & Choppin, 1962; Mussgay & Weibel, 1962; Dales, 1963 ...

The bacterial cell envelope [PDF]
Antonie van Leeuwenhoek, a draper from Delft, using a tiny homemade microscope, first described microbes or ‘animalcules’ in a number of letters to the Royal Society. The letters specifically describe ‘animalcules’ in pepper water in 1676 (published 1677). The famous drawing of a swimming animalcule from a scraping of his teeth was in a letter of 1684 (

Drug-Resistant Tuberculosis 2020: Where We Stand
The control of tuberculosis (TB) is hampered by the emergence of multidrug-resistant (MDR) Mycobacterium tuberculosis (Mtb) strains, defined as resistant to at least isoniazid and rifampin, the two bactericidal drugs essential for the treatment of the ...
