title: Purification of a positive regulatory subunit from phage SP01-modified RNA polymerase.
abstract: A phage-induced subunit has been purified from phage SP01-modified Bacillus subtilis RNA polymerase. This subunit binds in vitro to RNA polymerase core from uninfected B. subtilis thereby template-selective transcription and asymmetric synthesis of SP01 middle RNA.
