Abstract

The COOH terminus of the externally disposed variant surface glycoprotein (VSG) of the eukaryotic pathogenic protozoan Trypanosoma brucei strain 427 variant MITat 1.4 (117) is covalently linked to a novel phosphatidylinositol-containing glycolipid. This conclusion is supported by analysis of the products of nitrous acid deamination or Staphylococcus aureus phosphatidylinositol-specific phospholipase C treatment of purified membrane-form VSG. Lysis of trypanosomes is accompanied by release of soluble VSG, catalyzed by activation of an endogenous phospholipase C. The only apparent difference between membrane-form VSG and soluble VSG is the removal of sn-1,2-dimyristylglycerol. The COOH-terminal glycopeptide derived by Pronase digestion of soluble VSG was characterized by chemical modification and digestion with alkaline phosphatase. The results are consistent with the single non-N-acetylated glucosamine residue being the reducing terminus of the oligosaccharide and in a glycosidic linkage to a myo-inositol monophosphate that is probably myo-inositol 1,2-cyclic monophosphate. A partial structure for the VSG COOH-terminal moiety is presented. This structure represents a new type of eukaryotic post-translational protein modification and membrane anchor. We discuss the relevance of this structure to observations that have been made with other eukaryotic membrane proteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
