Archaea in der Biotechnologie [PDF]

BIOspektrum, 2021
AbstractArchaea are prokaryotic organisms with highly interesting physiological features. They have also shown potential for the production of biotechnological compounds. Today, the commercially available products of archaea are bacterioruberin, squalene, bacteriorhodopsin, and lipids — all of which are produced by utilizing halophilic archaea.

Metabolism of halophilic archaea [PDF]

Extremophiles, 2008
In spite of their common hypersaline environment, halophilic archaea are surprisingly different in their nutritional demands and metabolic pathways. The metabolic diversity of halophilic archaea was investigated at the genomic level through systematic metabolic reconstruction and comparative analysis of four completely sequenced species: Halobacterium ...

Ancestral Reconstructions Decipher Major Adaptations of Ammonia-Oxidizing Archaea upon Radiation into Moderate Terrestrial and Marine Environments

mBio, 2020
Unlike all other archaeal lineages, ammonia-oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread and abundant in all moderate and oxic environments on Earth. The evolutionary adaptations that led to such unprecedented ecological success of

Putative Nucleotide-Based Second Messengers in the Archaeal Model Organisms Haloferax volcanii and Sulfolobus acidocaldarius

Frontiers in Microbiology, 2021
Research on nucleotide-based second messengers began in 1956 with the discovery of cyclic adenosine monophosphate (3′,5′-cAMP) by Earl Wilbur Sutherland and his co-workers.

Enzymatic Switching Between Archaeal DNA Polymerases Facilitates Abasic Site Bypass

Frontiers in Microbiology, 2021
Abasic sites are among the most abundant DNA lesions encountered by cells. Their replication requires actions of specialized DNA polymerases. Herein, two archaeal specialized DNA polymerases were examined for their capability to perform translesion DNA ...

A Well-Conserved Archaeal B-Family Polymerase Functions as an Extender in Translesion Synthesis

mBio, 2022
B-family DNA polymerases (PolBs) of different groups are widespread in Archaea, and different PolBs often coexist in the same organism. Many of these PolB enzymes remain to be investigated.

Roadmap for naming uncultivated Archaea and Bacteria

Nature Microbiology, 2020
The assembly of single-amplified genomes (SAGs) and metagenome-assembled genomes (MAGs) has led to a surge in genome-based discoveries of members affiliated with Archaea and Bacteria, bringing with it a need to develop guidelines for nomenclature of ...

Cyclic nucleotides in archaea: Cyclic di‐AMP in the archaeon Haloferax volcanii and its putative role

MicrobiologyOpen, 2019
The role of cyclic nucleotides as second messengers for intracellular signal transduction has been well described in bacteria. One recently discovered bacterial second messenger is cyclic di‐adenylate monophosphate (c‐di‐AMP), which has been demonstrated

Archaea on Human Skin

PLoS ONE, 2013
The recent era of exploring the human microbiome has provided valuable information on microbial inhabitants, beneficials and pathogens. Screening efforts based on DNA sequencing identified thousands of bacterial lineages associated with human skin but provided only incomplete and crude information on Archaea.

CRISPR-mediated gene silencing reveals involvement of the archaeal S-layer in cell division and virus infection

Nature Communications, 2019
The S-layer is a proteinaceous envelope often found in bacterial and archaeal cells. Here, the authors use CRISPR-based technology to silence slaB, encoding the S-layer membrane anchor, to show that an intact S-layer is important for cell division and ...
