Ultrastructure of lipopolysaccharide isolated from Thermoplasma acidophilum [PDF]
The fine structure of lipopolysaccharide isolated from Thermoplasma acidophilum was examined by electron microscopy. Negative staining of the lipopolysaccharide revealed long, ribbon-like structures with some branching. The average width of the lipopolysaccharide ribbons was 5 nm.

Impact of age-associated cyclopurine lesions on DNA repair helicases. [PDF]
8,5' cyclopurine deoxynucleosides (cPu) are locally distorting DNA base lesions corrected by nucleotide excision repair (NER) and proposed to play a role in neurodegeneration prevalent in genetically defined Xeroderma pigmentosum (XP) patients.

The DNA-binding protein HTa from Thermoplasma acidophilum is an archaeal histone analog
Histones are a principal constituent of chromatin in eukaryotes and fundamental to our understanding of eukaryotic gene regulation. In archaea, histones are widespread but not universal: several lineages have lost histone genes.

Ubiquitin found in the archaebacterium Thermoplasma acidophilum
Systematic N‐terminal sequencing of the low molecular weight proteins from Thermoplasma acidophilum separated by two‐dimensional polyacrylamide get electrophoresis led to the discovery of a polypeptide with an apparent M r of 4.5 kDa identical as its first 18 amino acid residues to human ubiquitin.

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

Biosulfidogenesis Mediates Natural Attenuation in Acidic Mine Pit Lakes
Acidic pit lakes are abandoned open pit mines filled with acid mine drainage (AMD)—highly acidic, metalliferous waters that pose a severe threat to the environment and are rarely properly remediated.

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

Structure of thermoplasmaquinone from Thermoplasma acidophilum [PDF]
The structure of the methyl-substituted menaquinone (designated thermoplasmaquinone) from the extremely thermophilic and acidophilic archaebacterium Thermoplasma acidophilum was investigated by mass spectrometry and proton nuclear magnetic resonance spectrometry. The results of the present study show that the novel quinone from T.
