Cathepsin C (dipeptidyl peptidase I) is the physiological activator of a group of serine proteases. This domain corresponds to the exclusion domain whose structure excludes the approach of a polypeptide apart from its termini. It forms an enclosed beta barrel structure composed from 8 anti-parallel beta strands [1]. Based on a structural comparison and interaction data, it is suggested that the exclusion domain originates from a metallo-protease inhibitor [1].	Domain
