Plasmepsin

spinqualitylabelsall models Plasmepsin II complex with a potential antimalarial drug (PDB entry 4cku) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Plasmepsin (Plm) is a hemoglobin-degrading enzyme produced by the plasmodium parasite. It is an aspartic acid protease having 2 aspartic acid residues in the active site. Ten Plm isoforms are known which are named Plm I, II, etc and Histo-Aspartic Protease (HAP). Proplasmepsin II exhibits a large shift between its domains which renders the protease inactive. Relevance Plm is a potential target for anti-malaria drugs. Structural highlights The active site of Plm II contains a catalytic dyad of 2 Asp residues which interact with potential antimalarial inhibitor. Whole active site. Water molecules shown as red spheres.
