Malaria is one of the most dangerous tropical diseases of our time with more than one million deaths per annum. The worst form of malaria, the malaria tropica, is caused by the parasite Plasmodium falciparum. However some genetic mutations or enzymopathies like glucose-6-phosphate dehydrogenase (G6PDH) deficiency are leading to a protection against severe falciparum malaria. Additionally G6PDH deficiency is causing a severe issue during drug discovery against malaria due to enhanced oxidative stress. Increased oxidative stress levels are harming cells by creating xenobiotics from cellular molecules. The detoxification of xenobiotics as well as applied drugs are carried out e.g. by coupling glutathione (GSH) to the respective molecules. Recently a novel type of glutathione S-transferases PfEXP1/GST2 has been discovered which is considered to be one potential target of the frontline malaria drug artemisinin. The proposed project intents to shed light on the plasmodial protein EXP1/GST2 in xenobiotic detoxification and G6PDH deficiency. (AU)
