Pressures in archaeal protein coding genes: a comparative study [PDF]
Comparative and Functional Genomics, 2003 AbstractOur studies on the bases of codons from 11 completely sequenced archaeal genomes show that, as we move from GC‐rich to AT‐rich protein‐coding gene‐containing species, the differences between G and C and between A and T, the purine load (AG content), and also the overall persistence (i.e.

Genome editing in archaeal viruses and endogenous viral protein purification [PDF]
STAR Protocols, 2021 Archaea-infecting viruses are morphologically and genomically among the most diverse entities. Unfortunately, they are also fairly understudied due to a lack of efficient genetic tools. Here, we present a detailed protocol for the CRISPR/Cas-based genome editing of the virus SIRV2 infecting the genus Sulfolobus, which could easily be adapted to other ...

Protein-Protein Interaction Changes in an Archaeal Light-Signal Transduction [PDF]
Journal of Biomedicine and Biotechnology, 2010 Negative phototaxis inNatronomonas pharaonisis initiated by transient interaction changes between photoreceptor and transducer.pharaonisphoborhodopsin (ppR; also calledpharaonissensory rhodopsin II,psR-II) and the cognate transducer protein,pHtrII, form a tight 2 : 2 complex in the unphotolyzed state, and the interaction is somehow altered during the ...

Phylogenetic differences in content and intensity of periodic proteins [PDF]
, 2005 Many proteins exhibit sequence periodicity, often correlated with a visible structural periodicity. The statistical significance of such periodicity can be assessed by means of a chi-square-based test, with significance thresholds being calculated from ...

A comprehensive analysis of the importance of translation initiation factors for Haloferax volcanii applying deletion and conditional depletion mutants [PDF]
, 2013 Translation is an important step in gene expression. The initiation of translation is phylogenetically diverse, since currently five different initiation mechanisms are known.

Identification of Archaea-specific chemotaxis proteins which interact with the flagellar apparatus
BMC Microbiology, 2009 Background Archaea share with bacteria the ability to bias their movement towards more favorable locations, a process known as taxis. Two molecular systems drive this process: the motility apparatus and the chemotaxis signal transduction system.

Global analysis of viral infection in an archaeal model system
Frontiers in Microbiology, 2012 The origin and evolutionary relationship of viruses is poorly understood. This makes archaeal virus-host of particular interest because the hosts generally root near the base of phylogenetic trees, while some of the viruses have clear structural ...

Ribonucleolytic resection is required for repair of strand displaced nonhomologous end-joining intermediates [PDF]
, 2013 Nonhomologous end-joining (NHEJ) pathways repair DNA double-strand breaks (DSBs) in eukaryotes and many prokaryotes, although it is not reported to operate in the third domain of life, archaea. Here, we describe a complete NHEJ complex, consisting of DNA

Promiscuous behaviour of archaeal ribosomal proteins: Implications for eukaryotic ribosome evolution
Nucleic Acids Research, 2012 In all living cells, protein synthesis occurs on ribonucleoprotein particles called ribosomes. Molecular models have been reported for complete bacterial 70S and eukaryotic 80S ribosomes; however, only molecular models of large 50S subunits have been ...
