Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis

BMC Genomics, 2007
Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.

Study of the distribution of autotrophic CO2 fixation cycles in Crenarchaeota

, 2009
Two new autotrophic carbon fixation cycles have been recently described in Crenarchaeota. The 3-hydroxypropionate/4-hydroxybutyrate cycle using acetyl-coenzyme A (CoA)/propionyl-CoA carboxylase as the carboxylating enzyme has been identified for (micro ...

Cbp1 and Cren7 form chromatin-like structures that ensure efficient transcription of long CRISPR arrays

Nature Communications
CRISPR arrays form the physical memory of CRISPR adaptive immune systems by incorporating foreign DNA as spacers that are often AT-rich and derived from viruses. As promoter elements such as the TATA-box are AT-rich, CRISPR arrays are prone to harbouring

A Neighbour-joining tree for the thermopsin family A5.

, 2013
The tree was generated from the alignment of peptidase domains using FastTree. Labels are species names and sequence identifiers from the MEROPS database. Classification is indicated by coloured dots: yellow = Sulfolobales; red = Euryarchaeota; dark blue

Genome analysis of the thermoacidophilic archaeon Acidianus copahuensis focusing on the metabolisms associated to biomining activities [PDF]

, 2019
Background: Several archaeal species from the order Sulfolobales are interesting from the biotechnological point of view due to their biomining capacities.

The Microbial Biorealm: Sulfolobales

This website operated by Kenyon College contains brief descriptive information regarding the ecology, taxonomy, genome structure, cell structure and metabolism and significance of Sulfolobales, a thermophilic acidophile. Sulfolobales grow in terrestrial

Type IV pili dependent DNA repair in Sulfolobales [PDF]

, 2013
Het proefschrift van Matgorzata Ajon beschrijft een nieuw UV-induceerbaar DNA-uitwisselingssysteem in Sulfolobus-soorten. Deze organismen zijn hyperthermofiele Crenarchaeota die onder extreem hete en zure omstandigheden leven.

Comparison of gene organization in the region that surrounds the 16S rRNA gene in seven different Sulfolobales.

, 1998
Stability in genome organization has been widely studied by comparing physical and genetic maps of different genomes and, by comparing complete sequences from different genomes.

Arsenic Biomineral Formation Leads to Partial Encrustation of Thermoacidophilic Archaeon

, 2011
Acidophilic iron oxidizing Sulfolobales spp. can mediate the formation of jarosite nanoprecipitates and precursors of the arsenic biomineral scorodite [1]. In batch experiments, scorodite formation by Sulfolobales spp.

Labeling and Enzyme Studies of the Central Carbon Metabolism in Metallosphaera sedula

, 2011
Metallosphaera sedula ( Sulfolobales , Crenarchaeota ) uses the 3-hydroxypropionate/4-hydroxybutyrate cycle for autotrophic carbon fixation. In this pathway, acetyl-coenzyme A (CoA) and succinyl-
