Genes encoding the 7S RNA and tRNA^S^e^r are linked to one of the two rRNA operons in the genome of the extremely thermophilic archaebacterium Methanothermus fervidus

Analysis of gene structure in the extremely thermophilic archaebacterium, Methanothermus fervidus, has revealed the presence of a cluster of stable RNA-encoding genes arranged 5'-7S RNA-tRNA^S^e^r-16S rRNA-tRNA^A^l^a-23S rRNA-5S rRNA. The genome of M. fervidus contains two rRNA operons but only one ... Ausführliche Beschreibung

Zusammenfassung: Analysis of gene structure in the extremely thermophilic archaebacterium, Methanothermus fervidus, has revealed the presence of a cluster of stable RNA-encoding genes arranged 5'-7S RNA-tRNA^S^e^r-16S rRNA-tRNA^A^l^a-23S rRNA-5S rRNA. The genome of M. fervidus contains two rRNA operons but only one operon has the closely linked 7S RNA-encoding gene. The sequences upstream from the two rRNA operons are identical for 206 bp but diverge at the 3' base of the tRNA^S^e^r gene. The secondary structures predicted for the M. fervidus 7S, 16S rRNA, tRNA^A^l^a and tRNA^S^e^r have been compared with those of functionally homologous molecules from moderately thermophilic and mesophilic archaebacteria. A consensus secondary structure for archaebacterial 7S RNAs has been developed which incorporates bases and structural features also conserved in eukaryotic signal-recognition-particle RNAs and eubacterial 4.5S RNAs.
