title: Characterization of the 23S and 5S rRNA genes of Coxiella burnetii and identification of an intervening sequence within the 23S rRNA gene.
abstract: 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 molecules suggests that the loop is removed. An open reading frame in the IVS has been identified that shows 70% similarity at the amino acid level to IVS open reading frames characterized from four species of Leptospira.
