Fusion of the promoter region of rRNA operon rrnB to lac Z gene.
نویسندگان
چکیده
A Lambda phage was constructed in which the structural gene for beta galactosidase is fused to a DNA segment carrying the ribosomal promoter rrnB of E. coli. In this hybrid operon beta galactosidase synthesis in vitro is repressed by ppGpp. Repression of beta galactosidase synthesis by cAMP is reported.

Distinct types of rRNA operons exist in the genome of the actinomycete Thermomonospora chromogena and evidence for horizontal transfer of an entire rRNA operon.
We describe here the presence of two distinct types of rRNA operons in the genome of a thermophilic actinomycete Thermomonospora chromogena. The genome of T. chromogena contains six rRNA operons (rrn), of which four complete and two incomplete ones were cloned and sequenced. Comparative analysis revealed that the operon rrnB exhibits high levels of sequence variations to the other five nearly i...
متن کاملStrategies used by pathogenic and nonpathogenic mycobacteria to synthesize rRNA.
One rRNA operon of all mycobacteria studied so far is located downstream from a gene thought to code for the enzyme UDP-N-acetylglucosamine carboxyvinyl transferase (UNAcGCT), which is important to cell wall synthesis. This operon has been designated rrnAf for fast-growing mycobacteria and rrnAs for slow growers. We have investigated the upstream sequences and promoter activities of rrnA operon...
متن کاملRates and consequences of recombination between rRNA operons.
A mutant strain of Escherichia coli was created by inserting a cassette encoding sucrose sensitivity and neomycin resistance (sacB-neo) into the small-subunit rRNA-encoding gene rrs in the rrnB operon. During growth in a complex medium, the cassette was lost from the population, and a complete rrs gene was restored at a rate of 5 x 10(-9) per cell division. Repair of this lesion required flanki...
متن کاملTranscriptional analysis of Bacillus subtilis rRNA-tRNA operons. I. The tRNA gene cluster of rrnB has an internal promoter.
Although the sequence and organization of many Bacillus subtilis tRNA genes are known, primary transcripts from these regions have not been previously analyzed. In this paper, S1 nuclease mapping, S1-type mapping, and Northern analyses were applied to the end of the 23 S rRNA, the 5 S rRNA, and the 21 tRNA genes of B. subtilis operon rrnB. Primary transcripts from the 5 S rRNA and tRNA genes up...
متن کاملMechanisms of streptomycin resistance: selection of mutations in the 16S rRNA gene conferring resistance.
Chromosomally acquired streptomycin resistance is frequently due to mutations in the gene encoding the ribosomal protein S12, rpsL. The presence of several rRNA operons (rrn) and a single rpsL gene in most bacterial genomes prohibits the isolation of streptomycin-resistant mutants in which resistance is mediated by mutations in the 16S rRNA gene (rrs). Three strains were constructed in this inv...
