Smithies, Gibbons, and Bayley reported a relatively high nitrogen content in the walls of several halophilic bacteria which indicated that the cell material was predominantly protein. They contained only small amounts of lipides. The cell walls were lipoprotein.

Some animal tissues and some unicellular organisms are rich in ether lipids, in which one of the two acyl chains is attached to glycerol in ether, rather than ester, linkage. The ether-linked chain may be saturated, as in the alkyl ether lipids, or may contain a double bond between C-l and C-2, as in plasmalogens (Fig. 10-9). Vertebrate heart tissue is uniquely enriched in ether lipids about half of the heart phospholipids are plasmalogens. The membranes of halophilic bacteria, ciliated protists, and certain invertebrates also contain high proportions of...

The incorporation of a membrane protein into a polymerizable liposome from (22) was demonstrated by R. Pabst n9). The chromoprotein bacteriorhodopsin — a light-driven proton pump from halophilic bacteria — was incorporated into monomeric sulfolipid liposomes by ultrasonication. The resulting proteoliposomes were poly-... 

Cells drive active transport in a variety of ways. The plasma-membrane Na+-K+ pump of animal cells (a) and the plasma-membrane H+ pump of anaerobic bacteria (b) are driven by the hydrolysis of ATP. Eukaryotic cells couple the uptake of neutral amino acids to the inward flow of Na+ (c). Uptake of /3-gal actosidcs by some bacteria is coupled to inward flow of protons (d). Electron-transfer reactions drive proton extrusion from mitochondria and aerobic bacteria (e). In halophilic bacteria, bacteriorhodopsin uses the energy of sunlight to pump protons (/). E. coli and some other bacteria phosphorylate glucose as it moves into the cell and thus couple the transport to hydrolysis of phosphoenolpyruvate (g).

Membranes of extremely halophilic bacteria oxidize NADH in the presence of a variety of redox dyes, including menadione [103] and DCIP [100]. The enzyme, which is located on the inner aspect of the cytoplasmic membrane [104], has been used as a marker of vesicle orientation [20]. However, a second marker should be used in conjunction with menadione reductase as there are indications that the location of the dehydrogenase may be randomized during membrane preparation [105]. A similar situation occurs with respect to the ATPase activities in Micrococcus lysodeikticus [106] and E. coli [75,107] as well as the NADH and succinate dehydrogenases from E. co/f [75,108]. The orientation of the NADH dehydrogenase in the case of H. saccharovorum does not correspond... 

There are other proteins from extremely halophilic bacteria that do not require high concentrations of salt for stability or activity [147-149]. This raises the possibility that there are additional proteins in the extreme halophiles that do not require conditions of high ionic strength for stability or activity. The failure to detect such proteins could be due to the conditions used during their isolation and characterization (i.e., high concentrations of salt) that are inimical to such enzymes.
