pubmed:abstractText |
By an experimental RNomics approach, we have generated a cDNA library from small RNAs expressed from the genome of the hyperthermophilic bacterium Aquifex aeolicus. The library included RNAs that were antisense to mRNAs and tRNAs as well as RNAs encoded in intergenic regions. Substantial steady-state levels in A.aeolicus cells were confirmed for several of the cloned RNAs by northern blot analysis. The most abundant intergenic RNA of the library was identified as the 6S RNA homolog of A.aeolicus. Although shorter in size (150 nt) than its gamma-proteobacterial homologs (approximately 185 nt), it is predicted to have the most stable structure among known 6S RNAs. As in the gamma-proteobacteria, the A.aeolicus 6S RNA gene (ssrS) is located immediately upstream of the ygfA gene encoding a widely conserved 5-formyltetrahydrofolate cyclo-ligase. We identifed novel 6S RNA candidates within the gamma-proteobacteria but were unable to identify reasonable 6S RNA candidates in other bacterial branches, utilizing mfold analyses of the region immediately upstream of ygfA combined with 6S RNA blastn searches. By RACE experiments, we mapped the major transcription initiation site of A.aeolicus 6S RNA primary transcripts, located within the pheT gene preceding ygfA, as well as three processing sites.
