Abstract

The malaria parasite Plasmodium falciparum possesses organelles such as mitochondrion and the chloroplast-like compartment named apicoplast which is absent in the human host. Interference with metabolic pathways present in the latter one have been proven be lethal for the parasite. During schizogony P. falciparum need to distribute this organelle to the newly generated merozites which requires the presence of specific proteins. We already identified an enzyme, MinD, belonging to the Min protein of plants. The protein is predicted to be trafficked to the apicoplast and to act as a phosphatase. The aim of the proposed application is to biochemically characterise the recombinant plasmodial enzyme and identify its role in organelle distribution by employing transgenic parasites over-expressing Strep-tagged MinD enzymes. Further mutagenic modifications of PfMinD over-expressing cells will be used to visualise morphological changes of the apicoplast of GFP expressing parasites. The discovery of proteins involved in organelle distribution is very likely to identify novel drug targets, which will be restricted to the parasite. (AU)
