N-Myristoylation

**Semantic type:** Molecular Function

**Definition:** N-Myristoylation is the covalent attachment of myristic acid, a saturated 14-carbon fatty acid inserted in the cytoplasmic leaflet of the lipid bilayer, by an amide linkage to the amino-terminal glycine residue of a protein in order to increase the hydrophobicity of some membrane proteins or to promote membrane localization of some cytoplasmic proteins.
