Multiple Plasmodium proteins and heme

The entry "Multiple Plasmodium proteins and heme" does not refer to a single canonical molecular target but rather to a collection of parasite proteins (especially enzymes involved in hemoglobin degradation and heme detoxification) and the heme molecule itself, together forming the malaria parasite’s heme detoxification pathway. During the intraerythrocytic stage, Plasmodium species degrade host hemoglobin, releasing toxic free heme, which must be efficiently detoxified to allow parasite survival. This is chiefly achieved via conversion to the inert crystal hemozoin in the parasite's food vacuole, a process involving a multi-enzyme complex that includes falcipain-2/2', plasmepsins, histo aspartic protease, heme detoxification protein, and possibly other ancillary proteins[2][4][7]. Heme and its subsequent sequestration as hemozoin have been central targets for some of the most effective antimalarial drugs, including chloroquine and artemisinin, which act by inhibiting heme polymerization or binding free heme, causing toxic build-up to the parasite[2][4]. Due to the plurality of proteins and chemical entities involved, and the fact that "multiple Plasmodium proteins and heme" describes a pathway (not a single molecular target), this entry is considered non-canonical and should be refined for structured data or drug-target mapping purposes.
