The Ompf sequence is a signaling peptide allowing for translocation of a protein to the periplasm

The E.coli K-12 strain possesses a protein, called the outer membrane protein F (Ompf). The precursor of this protein contains a signaling peptide 22 amino acids in length, which is the Ompf signaling sequence^[1]. This sequence is used for translocating proteins from the cytoplasm to the periplasm^[2]. For this reason, the Ompf sequence can be fused to other proteins for the secretion into the periplasm^[3].
