Opp binds polypeptides up to pentapeptide in length with high affinity. Opp is required for sporulation and competence. Opp carries oligopeptides to the membrane-associated oligopeptide permease. Structural highlights The bradykinin peptide is nestled between the 2 domains of Opp. Bradykinin peptide binding site. Cl coordination site. Water molecule is shown as red sphere.
