GPI anchor metabolic process

Term ID

GO:0006505

Synonyms

• glycosylphosphatidylinositol metabolic process
• glycosylphosphatidylinositol metabolism
• GPI anchor metabolism
• GPI/GSI anchor metabolic process
• GPI/GSI anchor metabolism

Definition

The chemical reactions and pathways involving glycosylphosphatidylinositol anchors, molecular mechanisms for attaching membrane proteins to the lipid bilayer of cell membranes. Structurally they consist of a molecule of phosphatidylinositol to which is linked, via the C-6 hydroxyl of the inositol, a carbohydrate chain. This chain is in turn linked to the protein through an ethanolamine phosphate group, the amino group of which is in amide linkage with the C-terminal carboxyl of the protein chain, the phosphate group being esterified to the C-6 hydroxyl of the terminal mannose of the core carbohydrate chain. 0198506732
