Oligopeptidases impose a size limitation on their substrates, the mechanism of which has long been in debate. Here we present the structure of a hexameric serine protease, an oligopeptidase from Pyrococcus horikoshii (PhAAP), revealing a complex, self-compartmentalized inner space, where substrates may access the monomer active sites passing through a double-gated "check-in" system: first passing through a pore on the hexamer surface, then turning to enter through an even smaller opening at the monomers' domain-interface. This substrate screening strategy is unique within the family. We found that among oligopeptidases a member of catalytic apparatus is positioned near an amylogenic beta-edge, which needs to be protected to prevent aggregation and found different strategies applied to such end. We propose that self-assembly within the family results in characteristically different substrate selection mechanisms coupled to different multimerization states.
