Bacillus subtilis transcriptional regulators interaction.
Bacillus subtilis aprE gene codes for the extracellular protease subtilisin. Its expression is controlled by AbrB, DegU, Hpr, SinI, SinR and Spo0A transition state protein regulators. To determine in vivo the protein-protein interactions among these regulators, we used the LexA-based bacterial genetic two-hybrid system. Our results show homo-dimerization to all the analyzed proteins and hetero-dimerization between SinR-SinI and SinR-Hpr.
