The chemical reactions and pathways resulting in the formation of phosphoinositides, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of inositol. A transamidation reaction that results in the cleavage of the polypeptide chain and the concomitant transfer of the GPI anchor to the newly formed carboxy-terminal amino acid of the anchored protein. The cleaved C-terminal contains the C-terminal GPI signal sequence of the newly synthesized polypeptide chain. The stepwise addition of the components of the GPI anchor on to phosphatidylinositol lipids in the endoplasmic reticulum membrane. The chemical reactions and pathways involving phosphoinositides, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of inositol. They are important constituents of cell membranes. The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-alanine ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of an alanyl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The covalent or non-covalent attachment of lipid moieties to an amino acid in a protein. The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-threonyl ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of a threonyl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-serine ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of a seryl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-cysteine ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of a cysteinyl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-glycine ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of a glycyl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-asparagine ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of a asparaginyl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The chemical reactions and pathways resulting in the formation of a glycosylphosphatidylinositol (GPI) anchor that attaches some membrane proteins to the lipid bilayer of the cell membrane. The phosphatidylinositol moiety is linked via the C-6 hydroxyl residue of inositol to a carbohydrate chain which is itself linked to the protein via an ethanolamine phosphate moiety, its amino group forming an amide linkage with the C-terminal carboxyl of the protein. Some GPI anchors have variants on this canonical linkage. The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-aspartic acid ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of a aspartyl-peptide bond in the carboxy-terminal region of a membrane-associated protein. The chemical reactions and pathways resulting in the formation of glycerophospholipids, any derivative of glycerophosphate that contains at least one O-acyl, O-alkyl, or O-alkenyl group attached to the glycerol residue. The chemical reactions and pathways resulting in the formation of any conjugated, water-soluble protein in which the nonprotein moiety consists of a lipid or lipids. 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 moiety, 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.

GO TERM SUMMARY

Name: GPI anchor biosynthetic process
Acc: GO:0006506
Aspect: Biological Process
Desc: The chemical reactions and pathways resulting in the formation of a glycosylphosphatidylinositol (GPI) anchor that attaches some membrane proteins to the lipid bilayer of the cell membrane. The phosphatidylinositol moiety is linked via the C-6 hydroxyl residue of inositol to a carbohydrate chain which is itself linked to the protein via an ethanolamine phosphate moiety, its amino group forming an amide linkage with the C-terminal carboxyl of the protein. Some GPI anchors have variants on this canonical linkage.
