Fig. 6From: Newly discovered clouting interplay between matrix metalloproteinases structures and novel quaternary Ammonium K21: computational and in-vivo testingA The quaternary ammonium silane attaches at specific pockets on MMPs producing a “Clouting motion effect” preventing the attachment of other ligands. B The arrows indicate attachment of K21 chain on various clefts on MMP surfaces. The QAS molecule depicts a smacking by this attachment all over the MMP active sites preventing other molecules to ascribe on MMP structure.
