Characterization of Thermoplasma acidophilum Deoxyribonucleic Acid [PDF]

International Journal of Systematic Bacteriology, 1975
The deoxyribonucleic acid (DNA) of the mycoplasma Thermoplasma acidophilum has a base composition of 46 mol% guanine plus cytosine (G+C). Depurination can occur to the DNA in the culture conditions, giving rise to a product of lower buoyant density. This effect probably accounts for earlier descriptions of a much lower G+C content in the DNA.

Crystal Structure of a Nicotinate Phosphoribosyltransferase from Thermoplasma acidophilum [PDF]

Journal of Biological Chemistry, 2005
We have determined the crystal structure of nicotinate phosphoribosyltransferase from Themoplasma acidophilum (TaNAPRTase). The TaNAPRTase has three domains, an N-terminal domain, a central functional domain, and a unique C-terminal domain. The crystal structure revealed that the functional domain has a type II phosphoribosyltransferase fold that may ...

Proteomics Analysis of Thermoplasma acidophilum with a Focus on Protein Complexes [PDF]

Molecular & Cellular Proteomics, 2007
Two-dimensional gel electrophoresis (2DE) and MALDI-TOF MS were used to obtain a global view of the cytoplasmic proteins expressed by Thermoplasma acidophilum. In addition, glycerol gradient ultracentrifugation coupled to 2DE-MALDI-TOF MS analysis was used to identify subunits of macromolecular complexes.

Quinone Profiles of Thermoplasma acidophilum HO-62 [PDF]

Journal of Bacteriology, 2001
ABSTRACT Quinones of Thermoplasma acidophilum HO-62 were analyzed by high-performance liquid chromatography, mass spectrometry, and nuclear magnetic resonance. Menaquinone, methionaquinone, and 2- trans and 2- cis forms of thermoplasmaquinone were identified.

Cell-Free Enzymatic Conversion of Spent Coffee Grounds Into the Platform Chemical Lactic Acid

Frontiers in Bioengineering and Biotechnology, 2019
The coffee industry produces over 10 billion kg beans per year and generates high amounts of different waste products. Spent coffee grounds (SCG) are an industrially underutilized waste resource, which is rich in the polysaccharide galactomannan, a ...

Purification and properties of pyruvate kinase fromThermoplasma acidophilum [PDF]

FEMS Microbiology Letters, 1992
Thermoplasma acidophilum is a thermoacidophilic archaebacterium occupying a paradoxical place in phylogenetic trees (phenotypically it is a thermoacidophile but phylogenetically it classifies with the methanogens). To better understand its phylogeny, the pyruvate kinase from this organism is being investigated as a molecular marker. The enzyme has been

Architectures of archaeal GINS complexes, essential DNA replication initiation factors

BMC Biology, 2011
Background In the early stage of eukaryotic DNA replication, the template DNA is unwound by the MCM helicase, which is activated by forming a complex with the Cdc45 and GINS proteins.

Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis

BMC Genomics, 2007
Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.

Extending Cofactor‐Tethered Nanomachines to Complex Multienzyme Redox Cascades in Continuous Flow

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Engineered enzyme fusions bearing covalently tethered PEG–nicotinamide cofactors enable intramolecular cofactor retention and recycling within self‐sufficient biocatalytic nanomachines. These nanomachines support cofactor‐autonomous operation of complex redox multienzyme cascades under continuous‐flow conditions, as demonstrated in a 10‐step glucose‐to‐
