Abstract

The purified TyrR protein and phenylalanine were sufficient to activate in vitro transcription from the tyrP promoter by wild-type RNA polymerase. Such TyrR-mediated activation did not occur when the mutant alpha 235 RNA polymerase was used, indicating that TyrR is a class I transcription activator.
