Abstract

The major macromolecule on the surface of the protozoan parasite Leishmania major is a lipophosphoglycan (LPG) which contains a glycosylphosphatidylinositol glycolipid anchor. This parasite also synthesizes a complex family of abundant low-molecular-mass glycoinositolphospholipids (GIPLs) which are structurally related to the LPG anchor. In this study, L. major promastigotes were metabolically labelled with [3H]GlcN, and the kinetics of incorporation into free glycolipids and the LPG anchor followed to elucidate the pathway of GIPL biosynthesis and possible precursor-product relationships between the GIPLs and LPG. Labelled GIPLs were identified by TLC and by liquid chromatography of the rel..
