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.

A new phosphotriesterase from Sulfolobus acidocaldarius and its comparison with the homologue from Sulfolobus solfataricus

Biochimie, 2007
The phosphotriesterase PTE, identified in the soil bacterium Pseudomonas diminuta, is thought to have evolved in the last several decades to degrade the pesticide paraoxon with proficiency approaching the limit of substrate diffusion (k(cat)/K(M) of 4 x 10(7)M(-1)s(-1)).

Sulfolobus tokodaii sp. nov. (f. Sulfolobus sp. strain 7), a new member of the genus Sulfolobus isolated from Beppu Hot Springs, Japan

Extremophiles, 2002
The taxonomic position of a thermoacidophilic crenarchaeote Sulfolobus sp. strain 7, previously isolated from the Beppu Hot Springs in the geothermal area of Kyushu Island, Japan, was investigated by cloning and sequencing, by phylogenetic analysis of the 16S rRNA gene sequence, by DNA-DNA homology with similar species, and by biochemical ...

A novel single-tailed fusiform Sulfolobus virus STSV2 infecting model Sulfolobus species

Extremophiles, 2013
A newly isolated single-tailed fusiform virus, Sulfolobus tengchongensis spindle-shaped virus STSV2, from Hamazui, China, is characterised. It contains a double-stranded modified DNA genome of 76,107 bp and is enveloped by a lipid membrane structure. Virions exhibit a single coat protein that forms oligomers when isolated.

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.

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.

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 ...

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.

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.

Interactions of Sulfolobus acidocaldarius with uranium

Radiochimica Acta, 2010
Abstract Interactions of the acidothermophilic archaeon Sulfolobus acidocaldarius DSM 639 with U(VI) were studied by using a combination of batch experiments, X-ray absorption spectroscopy (XAS), and time-resolved laser-induced fluorescence spectroscopy (TRLFS).
