Abstract excerpt
In Escherichia coli, pyrimidine-mediated regulation of upp expression occurs by UTP-sensitive selection of alternative transcriptional start sites, which produces transcripts that differ in the ability to be elongated. The upp initially transcribed region contains the sequence GATTTTTTTTG (nontemplate strand). Initiation can occur at either the first or the second base in this sequence (designated G6 and A7, with...
