Stability of aspartate aminotransferase from Sulfolobus solfataricus [PDF]
Aspartate aminotransferase from Sulfolobus solfataricus (SsAspAT) is an extremely thermophilic and thermostable dimeric enzyme which retains its structure and reaches maximal activity at 100 degrees C. The structural stability of this protein was investigated by coupling isothermally and thermally induced denaturation studies to molecular modeling. Gel

Characterisation of Sulfolobus solfataricus Ard1, a promiscuous N-acetyltransferase [PDF]
Compaction of DNA into chromatin is an important feature of every living cell. This compaction phenomenon is brought about and maintained by a variety of DNA binding proteins, which have evolved to suit the specific needs of the different cell types ...

Ultrastructural and proteomic evidence for the presence of a putative nucleolus in an Archaeon
Nucleoli are subcellular compartments where transcription and maturation of pre-ribosomal RNAs occur. While the transcription of ribosomal RNAs is common to all living cells, the presence and ultrastructure of nucleoli has been only documented in ...

An HflX-type GTPase from Sulfolobus solfataricus binds to the 50S ribosomal subunit in all nucleotide-bound states [PDF]
HflX GTPases are found in all three domains of life, Bacteria, Archaea, and Eukaryotes. HflX from Escherichia coli has been shown to bind to the 50S ribosomal subunit in a nucleotide-dependent manner and this interaction strongly stimulates its GTPase ...

The Sulfolobus solfataricus P2 genome project
Over 800 kbp of the 3‐Mbp genome of Sulfolobus solfataricus have been sequenced to date. Our approach is to sequence subclones of mapped cosmids, followed by sequencing directly on cosmid templates with custom primers. Using a prototype automated system for genome‐scale analysis, known as MAGPIE, along with other tools, we have discovered one open ...

Peptidyl-tRNA hydrolase from Sulfolobus solfataricus [PDF]
An enzyme capable of liberating functional tRNA(Lys) from Escherichia coli diacetyl-lysyl-tRNA(Lys) was purified from the archae Sulfolobus solfataricus. Contrasting with the specificity of peptidyl- tRNA hydrolase (PTH) from E.coli, the S.solfataricus enzyme readily accepts E.coli formyl-methionyl-tRNA(fMet) as a substrate.

The transcript cleavage factor paralogue TFS4 is a potent RNA polymerase inhibitor
Transcript cleavage factors such as eukaryotic TFIIS assist the resumption of transcription following RNA pol II backtracking. Here the authors find that one of the Sulfolobus solfataricus TFIIS homolog—TFS4—has evolved into a potent RNA polymerase ...

A genetic study of SSV1, the prototypical fusellovirus.
Viruses of thermophilic Archaea are unique in both their structures and genomic sequences. The most widespread and arguably best studied are the lemon-shaped fuselloviruses.
