Evolutionary genomics of archaeal viruses: unique viral genomes in the third domain of life

Virus Research
D PrangishviliE V Koonin

Abstract

In terms of virion morphology, the known viruses of archaea fall into two distinct classes: viruses of mesophilic and moderately thermophilic Eueryarchaeota closely resemble head-and-tail bacteriophages whereas viruses of hyperthermophilic Crenarchaeota show a variety of unique morphotypes. In accord with this distinction, the sequenced genomes of euryarchaeal viruses encode many proteins homologous to bacteriophage capsid proteins. In contrast, initial analysis of the crenarchaeal viral genomes revealed no relationships with bacteriophages and, generally, very few proteins with detectable homologs. Here we describe a re-analysis of the proteins encoded by archaeal viruses, with an emphasis on comparative genomics of the unique viruses of Crenarchaeota. Detailed examination of conserved domains and motifs uncovered a significant number of previously unnoticed homologous relationships among the proteins of crenarchaeal viruses and between viral proteins and those from cellular life forms and allowed functional predictions for some of these conserved genes. A small pool of genes is shared by overlapping subsets of crenarchaeal viruses, in a general analogy with the metagenome structure of bacteriophages. The proteins encoded by t...Continue Reading

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.
