Mutational analysis of the regulatory region of the srfA operon in Bacillus subtilis

Abstract

Transcription of the Bacillus subtilis srfA operon is dependent on the transcriptional activator ComA. Mutational analysis of the srfA regulatory region suggests that two regions of dyad symmetry upstream of the srfA promoter may function in transcriptional activation by facilitating a cooperative interaction between ComA dimers.
