Function

PLM2_PLAFX During the asexual blood stage, participates in initial cleavage of native host hemoglobin (Hb) resulting in Hb denaturation (PubMed:11782538, PubMed:15574427, PubMed:8844673). May cleave preferentially denatured hemoglobin that has been cleaved by PMI (PubMed:8844673). Digestion of host Hb is an essential step which provides the parasite with amino acids for protein synthesis, and regulates osmolarity (Probable).^[1] ^[2] ^[3]
