Metabolism of Pentose Sugars in the Hyperthermophilic Archaea Sulfolobus solfataricus and Sulfolobus acidocaldarius [PDF]

Journal of Biological Chemistry, 2010
We have previously shown that the hyperthermophilic archaeon, Sulfolobus solfataricus, catabolizes d-glucose and d-galactose to pyruvate and glyceraldehyde via a non-phosphorylative version of the Entner-Doudoroff pathway. At each step, one enzyme is active with both C6 epimers, leading to a metabolically promiscuous pathway.

The Prefoldin of the Crenarchaeon Sulfolobus solfataricus

Protein & Peptide Letters, 2008
Prefoldin is a hetero-hexameric ATP-independent chaperone, shared by eukaryotes and archaea, which binds non-native proteins preventing them from aggregation. We report the identification and characterization in vivo and in vitro of the first prefoldin from a crenarchaeon, the hyperthermophile Sulfolobus solfataricus.

Purification and characterization of NADH oxidase from the archaea Sulfolobus acidocaldarius and Sulfolobus solfataricus

Biotechnology and Applied Biochemistry, 1996
The enzyme NADH oxidase (EC 1.6.99.3) has been isolated from the two thermoacidophilic archaea Sulfolobus acidocaldarius and Sulfolobus solfataricus and characterized. In both organisms the enzyme oxidizes specifically beta‐NADH in the presence of molecular oxygen and requires the presence of a flavin cofactor, showing a high specificity for FAD.

Carboxylase genes of Sulfolobus metallicus

Archives of Microbiology, 1999
Carbon dioxide limitation of Sulfolobus metallicus resulted in increased cellular concentrations of polypeptides that were predicted to be biotin carboxylase and biotin carboxyl-carrier-protein components of a protein complex. These polypeptides were coeluted from a native polyacrylamide gel and were estimated at 19 and 59 kDa after separation by ...

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)).

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.

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.
