Protein: DNA-binding dual transcriptional regulator OmpR (P0AA19)
Organism: Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Function: Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes (By similarity). Plays a central role in both acid and osmotic stress responses. Binds to the promoter of both ompC and ompF; at low osmolarity it activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity)
Subcellular location: Cytoplasm
