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[1].
