Promoter (OmpR, positive)

Positively regulated, OmpR-controlled promoter. This promoter is taken from the upstream region of ompC. Phosphorylated OmpR binds to the three operator sites and activates transcription.

Usage and Biology

In nature, this promoter is upstream of the ompC porin gene. The regulation of ompC is determined by the EnvZ-OmpR osmosensing machinery. EnvZ phosphorylates OmpR to OmpR-P. At high osmolarity, EnvZ is more active, creating more OmpR-P. OmpR-P then binds to the low-affinity OmpR operator sites upstream of ompC.
