TL;DR
Enzymatic treatment of the purified acylated protein established that the lipid is present as sn-1,2-diacyl glycerol, most probably linked to a phosphodiester at the 3-position of glycerl.
Abstract
The 195-kDa merozoite protein synthesized in schizonts of Plasmodium falciparum (Holder, A. A., and Freeman, R. R. (1982) J. Exp. Med. 156, 1528-1538) contains ester-linked fatty acid. Enzymatic treatment of the purified acylated protein established that the lipid is present as sn-1,2-diacyl glycerol, most probably linked to a phosphodiester at the 3-position of glycerol. The phosphodiglyceride is not directly esterified to an amino acid residue on the polypeptide backbone. The 195-kDa protein is processed to three fragments (83, 42, and 19 kDa) on the surface of free merozoites (Holder, A. A., and Freeman, R. R. (1984) J. Exp. Med. 160, 624-629), of which only the 42-kDa polypeptide is acylated.
