THE GENUS THERMOPLASMA*

Annals of the New York Academy of Sciences, 1973
Perhaps the organism we have isolated which has elicited the most interest (and some controversy) has been Thermoplasma. The credit for this organism goes first to Gary Darland, who was smart enough to recognize that something others would have considered to be a precipitate was indeed living, and to Robert Belly, who (among other important ...

Superoxide dismutase from the archaebacterium Thermoplasma acidophilum

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1981
Thermoplasma acidophilum is a mycoplasma-like thermophilic organism that has been classified with the archaebacteria. It has a single superoxide dismutase (superoxide : superoxide oxidoreductase, EC 1.15.1.1) which is composed of four identically sized subunits.

ζ-Potential and surface charge of Thermoplasma acidophila

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1977
The surface charge density and the zeta-potential of Thermoplasma acidophila was estimated from microscopic electrophoresis experiments. The cells moved towards the positive electrode. The mobility remained constant from pH 2 to 5, and increased for pH values higher than 6.

A new class of lipopolysaccharide from Thermoplasma acidophilum

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1974
Abstract A hot aqueous phenol extraction of lipid extracted whole cells of Thermoplasma acidophilum yielded a polymer that comprises 97% of the aqueous phase. The polymer is composed of 80% carbohydrate and 20% glycerol diether. Analysis of this polymer showed a ratio of 25:1:2 of carbohydrate: glycerol: alkane.

Glucosylcaldarchaetidylglycerol, a minor phosphoglycolipid from Thermoplasma acidophilum

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2000
A novel phosphoglycolipid (GPL-K) was isolated from Thermoplasma acidophilum (ATCC 27658). The chemical components of GPL-K were analyzed by gas liquid chromatography and GC-MS. The sugar moiety of GPL-K and its anomeric region were analyzed by NMR assignment.

[A new species of Thermoplasma].

Wei sheng wu xue bao = Acta microbiologica Sinica, 1995
An extremely thermoacidophilic strain, ES-23, was isolated from a self-heating coal spoil pile, Sichuan, China. The new isolate grows between 50 and 75 degrees C with optimum 70 degrees C and pH 1.0-5.0 with optimum 2.0. Strain ES-23 is aerobic and facultative autotrophic depending both heterotrophically on organic compounds and autotrophically on ...

Biochemical properties of the proteasome from Thermoplasma acidophilum

European Journal of Biochemistry, 1992
We have purified proteasomes to apparent homogeneity from the archaebacterium Thermoplasma acidophilum. This proteinase has a molecular mass of about 650 kDa and an isoelectric point of 5.6. The proteasome hydrolyses peptide substrates containing an aromatic residue adjacent to the reporter group, as well as [14C]methylated casein optimally at pH 8.5 ...

[52] Lipids of Thermoplasma

1982
Publisher Summary This chapter presents the procedures for the cultivation, isolation, and characterization of the diglyceryl tetraethers of Thermoplasma . Diglyceryl tetraethers are recovered from the nonsaponifiable fraction obtained by acid methanolysis of either whole cells, total lipids, or individual complex lipid species. Acid methanolysis is

Thermoplasma acidophilum: Intracellular pH and potassium concentration

Biochimica et Biophysica Acta (BBA) - General Subjects, 1976
Thermoplasma acidophilum is a free-living thermophilic mycoplasma. Although the organism lacks a cell wall, it can grow in medium as dilute as 66 mosM. The intracellular K+ concentration can be as low as 17 mM, but varies according to the osmolality of the culture medium.

Thermoplasma: a primordial cell from a refuse pile

Trends in Biochemical Sciences, 1982
Abstract A thermo-acidophilic archaebacterium is among the simplest of all known free-living microorganisms. Some of its features suggest that it might be related to the nucleus and cytoplasm of eukaryotic cells.
