Oligopeptide-binding protein: Difference between revisions

Revision as of 14:30, 8 June 2016

Function

Oligopeptide-binding protein (Opp) is a component of the

oligopeptide permease which is an ABC-type transporter system. 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^[1].

Structural highlights

The bradykinin peptide is nestled between the 2 domains of Opp^[2]. .
