=== Hinge domain ===
It corresponds to a short linker region from G242 to P258, with the following sequence: GLSSNPIQPTGPSTPKP, between the catalytic and the hemopexin domains. The exact role of this domain isn't very well clear but it's known that autoproteolysis could occurred in MMP8 leading to an unstable protein and different mutants<ref>http://www.sciencedirect.com/science/article/pii/S0014579397001580</ref> were made in the hinge region and it shown that stability of MMP8 could be increased, decreased or unchanged. Moreover, sequence alignements of collagenolytic MMPs in this hinge domain reveal that they all have the four prolines in the same positions, suggesting that these prolines could be important for the specific collagenolytic activity.
