Expression of functional Thermoplasma acidophilum proteasomes in Escherichia coli

FEBS Letters, 1992
The two genes encoding the constituent subunits of the Thermoplasma acidophilum proteasome were expressed in Escherichia coli yielding fully assembled molecules as shown by electron microscopy. The recombinant proteasomes were purified to homogeneity and

The crystal structure of glucose dehydrogenase from Thermoplasma acidophilum [PDF]

Structure, 1994
Background: The archaea are a group of organisms distinct from bacteria and eukaryotes. Structures of proteins from archaea are of interest because they function in extreme environments and because structural studies may reveal evolutionary relationships

The proteasome from Thermoplasma acidophilum is neither a cysteine nor a serine protease

FEBS Letters, 1995
The 20 S proteasome, found in eukaryotes and in the archaebacterium Thermoplasma acidophilum, forms the proteolytic core of the 26 S proteasome which is the central protease of the non-lysosomal protein degradation pathway, Inhibitor studies have ...

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.

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.

Histone-like protein in the prokaryote Thermoplasma acidophilum.

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1975
The DNA of the prokaryote Thermoplasma acidophilum is associated with a histone-like protein that has the following properties: it has a high content (23%) of basic amino acids, is positively charged at neutral pH, is soluble in acid, and can stabilize DNA against thermal denaturation.

Thermoplasma acidophilum and Thermoplasma volcanium sp. nov. from Solfatara Fields

Systematic and Applied Microbiology, 1988
Summary Twenty-three isolates of motile, cell wall-deficient, thermoacidophilic archaebacteria were obtained from hot acidic springs, soils and sediments within solfatara fields in the Azores, Iceland, Indonesia, Italy, and the United States. They are facultatively anaerobic organotrophs. Anaerobically, the isolates gain energy by sulfur respiration.

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.
