Notes:
The aprE gene of Bacillus subtilis encodes the major serine alkaline protease known as subtilisin. It is expressed during the transition state and transcribed by the σA form of the RNA polymerase (RNAP). In this work, we characterized the regulatory region of the aprE gene (rraprE) from B. subtilis. By computer analysis and site-directed mutagenesis, we localized the aprE promoter sequence 7 bp upstream from its transcription initiation site (TIS). We also characterized the static curvature properties of the rraprE DNA and found two different areas of DNA bending, within the first 400 bp upstream of its TIS. We postulate that these particular curved DNA regions could play a role in the interaction with some regulatory proteins and discuss possible implications related to aprE transcription regulation.
