The complete genome sequence of Thermoproteus tenax: a physiologically versatile member of the Crenarchaeota. [PDF]
PLoS ONE, 2011 Here, we report on the complete genome sequence of the hyperthermophilic Crenarchaeum Thermoproteus tenax (strain Kra1, DSM 2078(T)) a type strain of the crenarchaeotal order Thermoproteales.

Identification of a distinct family of polyphosphate kinases relevant to energy homeostasis in Crenarchaeota. [PDF]
J Biol ChemInorganic polyphosphate (polyP), a linear polymer of orthophosphate residues, occurs in all three domains of life and plays key roles in metabolism and regulation. While polyP metabolism has been well studied in bacteria and eukaryotes, studies in archaea have been limited, where the polyphosphate kinases (PPKs) involved in polyP synthesis remained ...

A Unique B-Family DNA Polymerase Facilitating Error-Prone DNA Damage Tolerance in Crenarchaeota
Frontiers in Microbiology, 2020 Sulfolobus islandicus codes for four DNA polymerases: three are of the B-family (Dpo1, Dpo2, and Dpo3), and one is of the Y-family (Dpo4). Western analysis revealed that among the four polymerases, only Dpo2 exhibited DNA damage-inducible expression.

Scientific Reports, 2021 Because ammonia-oxidizing archaea (AOA) are ubiquitous and highly abundant in almost all terrestrial soils, they play an important role in soil nitrification. However, the changes in the structure and function of AOA communities and their edaphic drivers

Structure and Spatial Heterogeneity of Chemosynthesis-Based Deep-Sea Archaeal and Bacterial Communities in Western South Atlantic. [PDF]
Ecol EvolWe report an extensive investigation of prokaryotic communities from a methane cold‐seep area in the Western South Atlantic Ocean (Southern Brazil) employing a broad sample set, including three distinct geographic areas (A, C and E) across a depth gradient (up to 18 m below the seafloor) related to the sulfate–methane transition zone (SMTZ).

Characterization of Fatty Acids in Crenarchaeota by GC-MS and NMR [PDF]
Archaea, 2015 Lipids composed of condensed isoprenyl units connected to glycerol backbones by ether linkages are a distinguishing feature of Archaea. Data suggesting that fatty acids with linear hydrocarbon chains are present in some Archaea have been available for decades.

Archaeal S-Layers: Overview and Current State of the Art
Frontiers in Microbiology, 2017 In contrast to bacteria, all archaea possess cell walls lacking peptidoglycan and a number of different cell envelope components have also been described.

Tropical aquatic Archaea show environment-specific community composition.
PLoS ONE, 2013 The Archaea domain is ubiquitously distributed and extremely diverse, however, environmental factors that shape archaeal community structure are not well known.

Novel Transcriptional Regulons for Autotrophic Cycle Genes in Crenarchaeota [PDF]
Journal of Bacteriology, 2015 ABSTRACT Autotrophic microorganisms are able to utilize carbon dioxide as their only carbon source, or, alternatively, many of them can grow heterotrophically on organics. Different variants of autotrophic pathways have been identified in various lineages of the phylum Crenarchaeota .

Nature Communications, 2016 Many microbial lineages have not yet been cultured, which hampers our understanding of their physiology. Here, Wurch et al. use single-cell genomics to infer cultivation conditions for the isolation of a tiny ectosymbiotic nanoarchaeon and its ...
