title: Sequence of the PR promoter of phage lambda.
abstract: The RNA polymerase binding site from the lambda PR promoter was isolated and sequenced. This DNA fragment contains the transcription initiation site and shares 25 nucleotides with OR. The sequence preceding the initiation site suggests that the promoter recognition site is not identical with the tight binding and initiation site.
