A region upstream from the Escherichia coli rrnB P1 promoter, the upstream activator region (UAR), increases the activity of the promoter in vivo and the rate of association with RNA polymerase (Eσ70) in vitro in the presence of the two initiating n

An upstream activation region (UAR) contributes to the extremely high activity of the Escherichia coli ribosomal RNA promoter, rrnB P1, increasing its activity 20- to 30-fold over that of the same promoter lacking the UAR. We have used DNase footprin

Transcription from the Escherichia coli rrnB P1 promoter is increased by a cis-acting sequence which extends upstream of the -35 hexamer to about -150 with respect to the transcription initiation site, the Upstream Activation Region (UAR). Activation
