Regulation of codBA operon expression in Escherichia coli by UTP-dependent reiterative transcription and UTP-sensitive transcriptional start site switching.

Abstract excerpt

Reiterative transcription is the repetitive addition of nucleotides to the 3' end of a nascent transcript due to slippage between the transcript and DNA template. Recently, we showed that pyrimidine-mediated regulation of pyrBI operon expression in Escherichia coli occurs, in part, through a mech...
