The structure of the membrane anchor of three Leishmania major surface antigenic glycolipids was analyzed. Phosphatidylinositol-specific phospholipase C treatment and nitrous acid deamination indicated the presence of a phosphatidylinositol anchor linked to the glycan through a non-N-acetylated hexosamine. An ester linkage on the C-2 of glycerol was revealed by phospholipase A2 hydrolysis. This fatty acyl substitution was not found on the phosphatidylinositol anchor of the Leishmania lipophosphoglycan.
