Plasmepsin (Plm) is a hemoglobin-degrading enzyme produced by the plasmodium parasite. It is a potential target for anti-malaria drugs. 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). ProPml II exhibits a large shift between its domains which renders the protease inactive. The images on the left and right correspond to one representative Plm structure, i.e. the Plasmepsin from Plasmodium falciparum (3fns).
