Definitions
Glycosylphosphatidylinositols (GPIs) are complex biomolecules containing carbohydrates, lipids, and phosphates that are attached to the C-terminus of proteins as a posttranslational modification in eukaryotes. GPIs are the major carbohydrate modification on the cell surface of Plasmodium falciparum and of crucial parasite membrane proteins. These glycolipids are known to contribute enormously to the pathogenicity of the parasite and affect the severity of the clinical symptoms of malaria. Additionally, the GPIs of P. falciparum contain some unique modifications that involve specific enzymatic steps in their biosynthesis and are ideal targets for the development of antimalarial drugs.
GPIs: General Introduction
Membrane proteins can be linked to the cell membrane as peripheral proteins that are temporarily associated with the membrane or as integral proteins that are linked through a hydrophobic...
