the results show that at least one of the phage spo1-coded subunits of the polymerase b-p determines selective transcription at the level of dna binding and rna chain initiation , weakens the binding of rna polymerase core to heterologous dna , and discriminates against promoter complex formation at certain promoters that are utilized by the b. subtilis holoenzyme .
