The modular gene architecture reflects the dual localization of PfAOP. Confocal live cell imaging of blood stage parasites expressing the indicated PfAOP-GFP chimera. The BTS is necessary and sufficient to target PfAOP to the apicoplast, as revealed by fluorescence microscopy and subcellular fractionation assays with transgenic parasites expressing different GFP-tagged PfAOP constructs. Removal of the N-terminus in PfAOPΔN-term-GFP abrogated the apicoplast targeting, whereas constructs with mutated methionine residues at the start of the Prx5 domain (PfAOPM71A/M77A-GFP) or without the C-terminal Prx5 domain (PfAOPBTS-GFP) were found exclusively in the apicoplast.Djuika CF, Huerta-Cepas J, Przyborski JM, Deil S, Sanchez CP, Doerks T, Bork P, Lanzer M, Deponte M.

Dual localization of PfAOP. (A) Immunofluorescence localization of PfAOP in blood stage parasites. (C) Co-localization analysis of PfAOP and a chimera of acyl-carrier protein and GFP (ACP-GFP) as an apicoplast-localized marker protein. Left, upper panel: a rather strong fluorescence was detected in the parasite cytosol. Left: Cytosolic or apicoplast localization of mutated and truncated GFP-tagged PfAOP. Additional confocal live cell images of blood stage parasites expressing the indicated PfAOP-GFP chimera. Early trophozoite to late schizont stage parasites are shown from top to bottom for each construct. Scale bar, 5 μm. Unprocessed full length PfAOP was not observed.Djuika CF, Huerta-Cepas J, Przyborski JM, Deil S, Sanchez CP, Doerks T, Bork P, Lanzer M, Deponte M.
