  • Title: Mapping of transcripts encoded by the plasmid in Chlamydia trachomatis.
    Author: Sriprakash KS, Pearce BJ.
    Journal: FEMS Microbiol Lett; 1990 Sep 15; 59(3):299-303. PubMed ID: 1703100.
    Abstract:
    Mapping of the plasmid-encoded RNA of the intracellular parasite, Chlamydia trachomatis revealed that the upstream control elements are different from those of other Gram-negative bacteria. A tetranucleotide, AYAA was found near the -10 position, in 5 out of 8 upstream sequences described so far. The plasmid also has a developmentally regulated promoter. The chlamydial upstream elements do not function as promoters in E. coli and vice versa. An E. coli promoter-like sequence has been found to occur fortuitously upstream from the plasmid-encoded dnaB gene. Such sequences may be evolutionary relics.
