[https://www.uniprot.org/uniprot/FPC3_PLAF7 FPC3_PLAF7] Cysteine protease which cleaves native host hemoglobin and globin in the food vacuole during the asexual blood stage (PubMed:11716777, PubMed:19357776). Preferentially cleaves substrates which have an arginine at the P1 position and a leucine at the P2 position (PubMed:19357776).<ref>PMID:11716777</ref> <ref>PMID:19357776</ref>

== Publication Abstract from PubMed ==
 +
Falcipain-2 and falcipain-3 are critical hemoglobinases of Plasmodium falciparum, the most virulent human malaria parasite. We have determined the 2.9 A crystal structure of falcipain-2 in complex with the epoxysuccinate E64 and the 2.5 A crystal structure of falcipain-3 in complex with the aldehyde leupeptin. These complexes represent the first crystal structures of plasmodial cysteine proteases with small molecule inhibitors and the first reported crystal structure of falcipain-3. Our structural analyses indicate that the relative shape and flexibility of the S2 pocket are affected by a number of discrete amino acid substitutions. The cumulative effect of subtle differences, including those at "gatekeeper" positions, may explain the observed kinetic differences between these two closely related enzymes.
