Subcellular localization of IscS and Isd11 to the mitochondrion of P. falciparum. A) Epifluorescent images of live P. falciparum erythrocytic-stage parasites expressing GFP fused to full-length IscS (IscSfl-GFP). The parasites were stained with mitotracker to identify mitochondria and DAPI to identify nuclei. Image z-stacks were deconvolved and then presented as a single combined image. Scale bar = 2 mm. B) Epifluorescent images similar to those in (A) of parasites expressing GFP fused to full length Isd11 (Isd11fl-GFP). IscS and Isd11 co-localize with mitotracker in all erythrocytic stages: late ring (top panels), late trophozoite or early schizont (middle panels), and schizont (lower panels) stage parasites. Lowest panel) Subcellular localization of the IscS leader peptide to the mitochondrion of P. falciparum. Epifluorescent images of live P. falciparum erythrocytic-stage parasites expressing GFP fused to the leader peptide of IscS (amino acids 1–35). The parasites were stained with mitotracker to identify mitochondria and DAPI to identify nuclei. Image z-stacks were deconvolved and then presented as a single combined image.
