We have investigated the transcriptional regulation and the interaction of the response regulator PhoP with the promoter regions of the PhoP-activated loci phoPQ , mgtA , slyB , pmrD , pcgL , phoN , pagC , and mgtCB .
Despite synthesizing the PhoP protein constitutively , there was no occupancy of PhoP-activated promoters ( Fig. 3C ) or transcription of PhoP-activated genes ( Fig. 3D ) in the strain with the -- 35 sequence in the phoPQ promoter growing under repressing conditions .
a regulated promoter is activated by the PhoP protein transcription in one with the wild-type phoPQ promoter -LSB- is , harboring the PhoP box is responsible for transcriptional autoregulation
