Stringent control in the archaeal genus Sulfolobus

Research in Microbiology, 2004
Six Archaea belonging to the phylum Euryarchaeota were previously analyzed with respect to stringent control. Only one of the strains studied was shown to possess Bacteria-like stringent control over stable RNA accumulation; ppGpp and pppGpp production was totally lacking in all Archaea analyzed.

The Genus Sulfolobus

1978
Our work on Sulfolobus originally arose out of a determination to find a natural habitat for Thermoplasma. As discussed in the previous chapter, Thermoplasma was originally discovered as an acidophilic thermophile living in self-heated coal refuse piles.

β-Glycosidase from Sulfolobus solfataricus

2001
Publisher Summary The hydrolysis of glycosidic bonds is crucial for several cell functions, such as energy uptake, cell wall expansion, and turnover of signaling molecules. Because the diversity of saccharides, there is a wide variety of glycosyl-hydrolases that have been classified in more than 74 families based on amino acid sequence similarities ...

Recombinant protein expression in Sulfolobus islandicus

2021
Since its invention, recombinant protein expression has greatly facilitated our understanding of various cellular processes in different biological systems because theoretically this technique renders any gene to be expressed in a mesophilic host like Escherichia coli, thus allowing functional characterizations of proteins of interest.

Structure of the S-layer of Sulfolobus acidocaldarius

Nature, 1982
The outermost component of many bacterial cell envelopes is a two-dimensional crystalline array of protein molecules, termed the S-layer1. Despite considerable effort to investigate its structure and composition, its precise function remains uncertain.

Sulfolobus genome: from genomics to biology

Current Opinion in Microbiology, 1998
Major progress in sequencing the genome of Sulfolobus solfataricus has been closely concerted with the characterization and sequencing of many extrachromosomal genetic elements, including viruses, cryptic plasmids and conjugative plasmids, as well as mobile archaeal introns and transposons.

Characterization of the Sulfolobus host–SSV2 virus interaction

Extremophiles, 2006
The Sulfolobus spindle virus, SSV2, encodes a tyrosine integrase which furthers provirus formation in host chromosomes. Consistently with the prediction made during sequence analysis, integration was found to occur in the downstream half of the tRNA(Gly) (CCC) gene.

[15] Alcohol dehydrogenase from Sulfolobus solfataricus

2001
Publisher Summary Alcohol dehydrogenases (ADHs) are enzymes widely distributed in all three domains of life: Eucarya, Bacteria, and Archaea. Three types of ADHs have been established: the medium-chain zinc-containing type I ADHs (∼370 residues), which are dimeric or tetrameric molecules and have been characterized in prokaryotes and many eukaryotes ...

An infB-Homolog in Sulfolobus acidocaldarius

Systematic and Applied Microbiology, 1996
Summary We have identified an archaeal homologue of the bacterial translation initiation factor 2 (IF-2 or inf B) in a partial open reading frame situated upstream of the gene cluster coding for the large subunits of the DNA-dependent RNA polymerase (RNAP) in Sulfolobus acidocaldarius .

Viruses of the extremely thermophilic archaeon Sulfolobus

Trends in Microbiology, 2001
Viruses of Sulfolobus are highly unusual in their morphology, and genome structure and sequence. Certain characteristics of the replication strategies of these viruses and the virus-host interactions suggest relationships with eukaryal and bacterial viruses, and the primeval existence of common ancestors.
