The Clustered Regularly Interspaced Short Palindromic Repeat System and Argonaute: An Emerging Bacterial Immunity System for Defense Against Natural Transformation?

Frontiers in Microbiology, 2020
Clustered regularly interspaced short palindromic repeat (CRISPR) systems and prokaryotic Argonaute proteins (Agos) have been shown to defend bacterial and archaeal cells against invading nucleic acids.

Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]

, 2019
Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

Archaeal DNA Repair Nucleases [PDF]

, 2011
DNA is the carrier of genetic information, but is constantly assaulted by endogenous and exogenous genotoxic attacks in all living organisms. If left unrepaired damaged or structurally altered DNA can impede pathways of DNA metabolism and maintenance of genomic stability and lead to cell death or uncontrolled proliferation.

Archaea Symbiont of T. cruzi Infection May Explain Heart Failure in Chagas Disease

Frontiers in Cellular and Infection Microbiology, 2018
Background: Archaeal genes present in Trypanosoma cruzi may represent symbionts that would explain development of heart failure in 30% of Chagas disease patients. Extracellular vesicles in peripheral blood, called exosomes (< 0.1 μm) or microvesicles (

Archaeal diversity in deep-sea sediments estimated by means of different Terminal-Restriction Fragment Length Polymorphisms (T-RFLP) protocols [PDF]

, 2009
Despite the increasing recognition of the quantitative importance of Archaea in all marine systems, the protocols for a rapid estimate of Archaeal diversity patterns in deep-sea sediments have been only poorly tested yet.

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 ...

Structure and Spatial Heterogeneity of Chemosynthesis-Based Deep-Sea Archaeal and Bacterial Communities in Western South Atlantic. [PDF]

Ecol Evol
We 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).

Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

A highly conserved family of inactivated archaeal B family DNA polymerases

Biology Direct, 2008
A widespread and highly conserved family of apparently inactivated derivatives of archaeal B-family DNA polymerases is described. Phylogenetic analysis shows that the inactivated forms comprise a distinct clade among archaeal B-family polymerases and ...
