Readthrough transcription beyond the terminators occurred with 5 and 30% efficiency, respectively, in E. coli and S. typhimurium. This difference is correlated with the stability of proposed secondary structures of the respective trp leader transcripts. Secondary structure analyses of the two leader transcripts revealed a well-conserved pattern of RNA base paring. This and the possibility that trp leader RNA is translated suggest a model for regulation of transcription termination that is based on ribosome movement along the RNA and a shift between alternative RNA base-pairing configuration.
