Structural Biochemistry/Enzyme Regulation/Myristoylation
One of the common covalent modifications of protein activity found in animals, palnts, and some viruses. It's donor molecule are Myristoyl CoA which is commonly used to modify protein called Src, main function of signal transduction. The myristoyl group is covalently attached to the N-terminal amino acid of a polypeptide. It is then catalyzed by the N-myristoyltransferase enzyme. It also plays an important role in membrane targeting in response to environmental stress on plants.
