RESUMO

Bacteriophage T4 gene 33 protein (gp33), which is required for viral late transcription, has been overproduced. The purified gp33 binds to RNA polymerase core from uninfected or T4-infected Escherichia coli, but the major E. coli transcription initiation factor, sigma 70, competed effectively for this binding.
