The Ribosomal RNA Operons of Halophilic Archaebacteria

Abstract

The comparative analysis of both 5S rRNA and small subunit rRNA sequences provided the first compelling evidence that archaeobacteria were a unique and coherent phylogenetic group, separate and distinct from both the eubacteria and the eucaryotes [1]. Within the archaebacteria, the extreme halophiles were shown to be a closely related phylogenetic clade and descendant from the anaerobic methanogens. As an alternative to using sequence comparison of structural RNAs and as part of an overall effort to characterize some of the unique features of halophilic archaebacteria at the molecular level, we have been examining the genetic organization and transcription of rRNA operons and the processing and assembly of the transcripts into ribosomal particles.
