Characterization of the 23S and 5S rRNA genes of Coxiella burnetii and identification of an intervening sequence within the 23S rRNA gene.
Characterization of the rRNA operon from the obligate intracellular bacterium Coxiella burnetii has determined the order of the rRNA genes to be 16S-23S-5S. A 444-bp intervening sequence (IVS) was identified to interrupt the 23S rRNA gene beginning at position 1176. The IVS is predicted to form a stem-loop structure formed by flanking inverted repeats, and the absence of intact 23S rRNA molecul...
متن کاملDiversity of 23S rRNA Genes within Individual Prokaryotic Genomes
BACKGROUND The concept of ribosomal constraints on rRNA genes is deduced primarily based on the comparison of consensus rRNA sequences between closely related species, but recent advances in whole-genome sequencing allow evaluation of this concept within organisms with multiple rRNA operons. METHODOLOGY/PRINCIPAL FINDINGS Using the 23S rRNA gene as an example, we analyzed the diversity among ...
متن کاملFragmentation of 23S rRNA in strains of Proteus and Providencia results from intervening sequences in the rrn (rRNA) genes.
Intervening sequences (IVSs) were originally identified in the rrl genes for 23S rRNA (rrl genes, for large ribosomal subunit, part of rrn operon encoding rRNA) of Salmonella enterica serovars Typhimurium LT2 and Arizonae. These sequences are transcribed but later removed during RNase III processing of the rRNA, resulting in fragmentation of the 23S species; IVSs are uncommon, but have been rep...
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
Intervening sequence acquired by lateral gene transfer in Tropheryma whipplei results in 23S rRNA fragmentation.
Completion of Tropheryma whipplei genome sequencing may provide insights into the evolution of the molecular mechanisms underlying the pathogenicity of this microorganism. The first postgenomic application was the successful design of a comprehensive culture medium that allows axenic growth of this bacterium, which is particularly recalcitrant to cultivation. This achievement in turn permitted ...
