Function

PLM2_PLAFX During the asexual blood stage, participates in initial cleavage of native host hemoglobin (Hb) resulting in Hb denaturation (PubMed:8844673, PubMed:11782538, PubMed:15574427). 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]

Publication Abstract from PubMed

Plasmepsin IV from Plasmodium falciparum (PM IV) is a promising target for the development of novel antimalarial drugs. Here, the crystal structure of the truncated zymogen of PM IV (pPM IV), consisting of the mature enzyme plus a prosegment of 47 residues, has been determined at 1.5 A resolution. pPM IV presents the fold previously described for studied proplasmepsins, displaying closer similarities to proplasmepin IV from P. vivax (pPvPM) than to the other two proplasmepsins from P. falciparum. The study and comparison of the pPM IV structure with the proplasmepsin structures described previously provide information about the similarities and differences in the inactivation-activation mechanisms among the plasmepsin zymogens.
