Abstract excerpt
Expression of the Escherichia coli pyrE gene is regulated by transcription attenuation in the intercistronic orfE-pyrE region and modulated by the distance between the transcribing RNA polymerase and the leading ribosome as a function of the supply of UTP and GTP. In this communication we show that pyrE expression is hyper-repressed in vivo following addition of uracil in strains carrying the nusAcs10 mutation....
