Regulator ctsr in Bacillus subtilis subsp. subtilis str. 168
Comment - binding to a directly repeated heptanucleotide operator sequence (A/GGTCAAANANA/GGTCAAA); three functional domains: HTH DNA-binding, dimerization, and putative heat-sensing domains; active as a dimer; specifically degraded by ClpP and ClpX at 37 degrees C; labile and substrate of the ClpCP protease under stress conditions (autoregulation by controlled proteolysis); negatively regulates its own synthesis
