چکیده

The 100 bp sequence from the beginning of the 16S rRNA gene of archaebacterium Halobacterium halobium and the adjacent 800 bp upstream sequence were determined. Four long (80 bp) direct repeats were found in the region preceeding the structural gene of the 16S rRNA. These repeats are proposed to constitute the promoter region of the rRNA operon of H. halobium.

Complex promoter pattern of the single ribosomal RNA operon of an archaebacterium Halobacterium halobium.

The transcription of the single ribosomal RNA gene cluster is initiated at an assemblage of promoters five of which were previously mapped in the 910 base pair region in front of the 16S rRNA gene. The nucleotide sequence between positions -1680 and -910 was determined and S1 nuclease mapping revealed therein two sites corresponding to the 5' ends of the primary transcripts. These two presumabl...

The number, physical organization and transcription of ribosomal RNA cistrons in an archaebacterium: Halobacterium halobium.

Because it is now clear that archaebacteria may be as distinct from eubacteria as either group is from eukaryotic cells, and because a specifically archaebacterial ancestry has been proposed for the nuclear-cytoplasmic component of eukaryotic cells, we undertook to characterize, for the first time, the ribosomal RNA cistrons of an archaebacterium (Halobacterium halobium). We found these cistron...

Common structural features of the genes for two stable RNAs from Halobacterium halobium

The genes coding for the 5S rRNA and another stable RNA, termed 7S RNA, in Halobacterium halobium were isolated from a genomic library of this archaebacterium and their nucleotide sequences determined. Both genes are colinear with their transcripts (5S rRNA and 7S RNA), but 5S rRNA and possibly also 7S RNA isolated from other halobacteria carry additional nucleotides within the RNA transcript. ...

Pactamycin resistance mutations in functional sites of 16 S rRNA.

Mutants of an archaeon Halobacterium halobium, resistant to the universal inhibitor of translation, pactamycin, were isolated. Pactamycin resistance correlated with the presence of mutations in the 16 S rRNA gene of H. halobium single rRNA operon. Three types of mutations were found in pactamycin resistant cells, A694G, C795U and C796U (Escherichia coli 16 S rRNA numeration) located distantly i...

Organization and nucleotide sequence of a gene cluster coding for eight ribosomal proteins in the archaebacterium Halobacterium marismortui.

A DNA fragment containing the genes for the eight ribosomal proteins HmaL3, HL6, HmaL23, HmaL2, HmaS19, HmaL22, HmaS3, and HmaL29 from Halobacterium marismortui has been cloned and sequenced. The organization of this gene cluster in general corresponds to the S10 operon of Escherichia coli although there exists some differences between them. The sequence analysis of the 5'- and 3'-region of the...
