UniProt

P0AA16 - OMPR_ECOLI

Protein:

Transcriptional regulatory protein OmpR
Protein Existence: Experimental evidence at protein level

Functioni

The N-terminus of this protein is required for the transcriptional expression of both major outer membrane protein genes ompF and ompC; its C-terminal moiety mediates the multimerization of the OmpR protein. As a multimer, it turns on the expression of the ompC gene; as a monomer, it turns on the expression of the ompF gene.
