pHHyDHODH-GFP Expression Plasmid

The pHHyDHODH-GFP expression plasmid is used to express dihydroorotate dehydrogenase (DHODH) fused to green fluorescent protein (GFP) in P. falciparum.


  • Expression of the DHODH-GFP fusion in P. falciparum is driven by a strong HSP86 5’UTR
  • Methotrexate-resistant human DHFR serves as a selectable marker for the plasmid in P. falciparum

Yeast DHODH and Aequorea GFPmut2 (1) coding sequences were inserted into an E. coli-Plasmodium falciparum shuttle plasmid (pHHMC*/3R0.5) (2), such that DHODH-GFP were fused into a single coding sequence (including a 10Ala-1Gly linker segment).
