== Publication Abstract from PubMed == | |||
Proplasmepsin II is the zymogen of plasmepsin II, an aspartic proteinase used by Plasmodiumfalciparum to digest hemoglobin during the blood stage of malaria. A large shift between the N-domain and the central and C-domains of proplasmepsin II opens the active site cleft, preventing the formation of a functional aspartic proteinase active site. This mode of inhibition of catalytic activity has not been observed in any other aspartic proteinase zymogen. Instead of occluding a pre-formed active site, as in the gastric aspartic proteinase zymogens, the prosegment of proplasmepsin II interacts extensively with the C-domain and serves as a 'harness' to keep the domains apart. Disruption of key salt bridges at low pH may be important in activation. | |||
