Widespread distribution of a 7S RNA in archaebacteria.

Abstract

An RNA of nonribosomal origin was found in the extreme halophilic bacteria. This novel small RNA was found to be a homogeneous species by RNA fingerprinting. Analysis of the ribonuclease T1 oligonucleotides gave no evidence of the presence of posttranscriptional modifications. Comparisons of electrophoretic mobility with other RNAs of known size suggest that this is a 7S RNA containing 325-375 nucleotides. An RNA of similar mobility was found in all major divisions of the archaebacteria. Insufficient sequence information is available to determine whether these RNAs are homologs of any other known small RNA.
