Occurrence of squalene, di- and tetrahydrosqualenes, and vitamin MK8 in an extremely halophilic bacterium, Halobacterium cutirubrum

Journal of Lipid Research, 1969
The nonpolar (acetone-soluble) lipids of the extremely halophilic bacterium, Halobacterium cutirubrum, were found to consist of red carotenoid pigments (43%) and squalenes (48%) with a small amount of a vitamin K-type quinone. The squalenes were shown by

Ion Transport of Biohybrid Asymmetric Membranes by pH and Light‐Cooperative Modulation

Advanced Materials Interfaces, 2020
Bacteriorhodopsin (bR) is an excellent light‐driven proton pump and plays a vital role in chemical and biological analytical processes, such as maintaining osmotic balance, intracellular acidity, and participating in photosynthesis.

Microbial Models in Screening of Inhibitors of Sterol Biosynthesis

Антибиотики и Химиотерапия, 2020
On the base of previously developed microbial models high effective scheme for screening of inhibitors of sterol biosynthesis (ISB) is proposed. It is based on cultivation of halophilic bacteria Halobacterium salinarum (former Halobacterium halobium ...

Ornithine Carbamoyltransferase from Halobacterium salinarium [PDF]

European Journal of Biochemistry, 1972
The enzymatic properties of purified ornithine carbamoyltransferase from Halobacterium salinarium have been studied and compared with those of the enzyme from non-halophilic organisms, and with those of other enzymes from halophilic organisms. The enzyme is stable and active in high concentrations of NaCl, KCl, RbCl and CsCl as are other enzymes

N-Glycosylation Is Important for Halobacterium salinarum Archaellin Expression, Archaellum Assembly and Cell Motility

Frontiers in Microbiology, 2019
Halobacterium salinarum are halophilic archaea that display directional swimming in response to various environmental signals, including light, chemicals and oxygen. In Hbt. salinarum, the building blocks (archaellins) of the archaeal swimming apparatus (

Early picosecond events in the photo cycle of Bacteriorhodopsin [PDF]

, 1986
The primary processes of the photochemical cycle of light-adapted bacteriorhodopsin (BR) were studied by various experimental techniques with a time resolution of 5 × 10-13 s. The following results were obtained.
