The helicase XPD unwinds bubble structures and is not stalled by DNA lesions removed by the nucleotide excision repair pathway

open access: yes, 2010
Xeroderma pigmentosum factor D (XPD) is a 5'-3' superfamily 2 helicase and the founding member of a family of DNA helicases with iron-sulphur cluster domains.

The Architecture and Chemical Stability of the Archaeal Sulfolobus Turreted Icosahedral Virus [PDF]

open access: yesJournal of Virology, 2010
ABSTRACT Viruses utilize a diverse array of mechanisms to deliver their genomes into hosts. While great strides have been made in understanding the genome delivery of eukaryotic and prokaryotic viruses, little is known about archaeal virus genome delivery and the associated particle changes. The Sulfolobus

Monitoring Physiological Changes in Haloarchaeal Cell during Virus Release

open access: yesViruses, 2016
The slow rate of adsorption and non-synchronous release of some archaeal viruses have hindered more thorough analyses of the mechanisms of archaeal virus release.

Game-Theoretical Modeling of Interviral Conflicts Mediated by Mini-CRISPR Arrays

open access: yesFrontiers in Microbiology, 2020
All cellular organisms coevolve with multiple viruses, so that both virus-host and intervirus conflicts are major factors of evolution. Accordingly, hosts evolve multiple, elaborate defense systems and viruses respond by evolving means of antidefense ...

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

open access: yesmLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Eukaryogenesis: The Rise of an Emergent Superorganism

open access: yesFrontiers in Microbiology, 2022
Although it is widely taught that all modern life descended via modification from a last universal common ancestor (LUCA), this dominant paradigm is yet to provide a generally accepted explanation for the chasm in design between prokaryotic and ...

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Viruses of archaea: Structural, functional, environmental and evolutionary genomics

open access: yes, 2018
International audienceViruses of archaea represent one of the most enigmatic parts of the virosphere. Most of the characterized archaeal viruses infect extremophilic hosts and display remarkable diversity of virion morphotypes, many of which have never ...
