Localization of apicoplast and mitochondrial LipDH. The localization of aLipDH and mLipDH was investigated by expressing the putative N-terminal presequences fused to GFP in P. falciparum intraerythrocytic parasites. A and B. Colocalization with antibodies directed against the apicoplast-resident acyl-carrier protein PFB0385w (ACP; A) and with MitoTracker Red (B) demonstrates that the putative apicoplast targeting presequence of aLipDH targets the marker protein GFP exclusively to the apicoplast. C–E. Colocalization experiments with the apicoplast protein ACP (C) and with the two mitochondrial markers MitoTracker Red and HSP60 PF10_0153 (D and E) indicate that mLipDH is localized exclusively in the mitochondrion.
