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.

A defined cultivation medium for Sulfolobus acidocaldarius.

Journal of Biotechnology, 2019
The thermoacidophilic Crenarchaeon Sulfolobus acidocaldarius is an important model organism for Archaea and genetic systems are well established. To date, the organism is routinely cultivated on complex media based on protein hydrolysates and no common defined medium is established. In this work we address this lack of a standardized defined medium and

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.

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 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)).

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 ...

Sulfolobus carboxypeptidase

2004
Publisher Summary This chapter describes the activity, specificity and structural chemistry of Sulfolobus carboxypeptidase. S. carboxypeptidase was subsequently purified to electrophoretic homogeneity and extensively characterized. In particular, specificity studies confirmed that it was able to cleave an N-blocked tripeptide. The S.

2-Propanol degradation by Sulfolobus solfataricus [PDF]

Biotechnology Letters, 2003
Sulfolobus solfataricus used 2-propanol and 2-propanone (acetone) when grown in static cultures at 78 degrees C with or without glucose at 10 g l-1. The presence of 3.92 g 2-propanol l-1 in both cases inhibited growth. However, acetone accumulation following 2-propanol depletion suggested that 2-propanol was co-metabolized via the acetone metabolic ...

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.
