EC Number 3.4.14.1
Enzyme Function FUNCTION: Thiol protease that cleaves dipeptides from the N-terminus of protein substrates (PubMed:15304495, PubMed:20833209). Active against a broad range of dipeptide substrates composed of both polar and hydrophobic amino acids (PubMed:20833209). Proline cannot occupy the P1 position and arginine or lysine cannot occupy the P2 position of the substrate (PubMed:20833209). Involved in host hemoglobin degradation by generating dipeptides from hemoglobin-derived oligopeptides (PubMed:15304495). {ECO:0000269|PubMed:15304495, ECO:0000269|PubMed:20833209}.

Induction
Subcellular Location SUBCELLULAR LOCATION: Vacuole lumen {ECO:0000269|PubMed:15304495}. Parasitophorous vacuole lumen {ECO:0000269|PubMed:15304495}. Note=In schizonts, the immature form localizes to the parasitophorous vacuole (PubMed:15304495). In trophozoites, the mature form localizes to the digestive (or food) vacuole, an acidic vacuole where host hemoglobin is digested (PubMed:15304495). {ECO:0000269|PubMed:15304495}.
