Haem Detoxification Pathway (Plasmodium falciparum) (HDP)

Target
HDP
Molecular classification
Enzyme, Metabolic Pathway
01

Overview

The haem detoxification pathway in *Plasmodium falciparum* is a crucial process for neutralizing toxic free haem released during hemoglobin digestion. It involves the polymerization of haem into inert hemozoin crystals within the food vacuole of the parasite. The Heme Detoxification Protein (HDP/PfHDP) is a key enzyme in this pathway, catalyzing the conversion of free haem to hemozoin. This pathway is essential for parasite survival and is targeted by several antimalarial drugs, including chloroquine and artemisinins. The pathway's uniqueness to Plasmodium makes it an attractive drug target.
