Metabolite Identification
Common NameTetradecanoyl-CoA
DescriptionTetradecanoyl-CoA (or myristoyl-CoA) is an intermediate in fatty acid biosynthesis, fatty acid elongation and the beta oxidation of fatty acids. It is also used in the myristoylation of proteins. The first pass through the beta-oxidation process starts with the saturated fatty acid palmitoyl-CoA and produces myristoyl-CoA. A total of four enzymatic steps are required, starting with VLCAD CoA dehydrogenase (Very Long Chain) activity, followed by three enzymatic steps catalyzed by enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and ketoacyl-CoA thiolase, all present in the mitochondria. Myristoylation of proteins is also catalyzed by the presence of myristoyl-CoA along with Myristoyl-CoA:protein N-myristoyltransferase (NMT). Myristoylation is an irreversible, co-translational (during translation) protein modification found in animals, plants, fungi and viruses. In this protein modification a myristoyl group (derived from myristioyl CoA) is covalently attached via an amide bond to the alpha-amino group of an N-terminal amino acid of a nascent polypeptide. It is more common on glycine residues but also occurs on other amino acids. Myristoylation also occurs post-translationally, for example when previously internal glycine residues become exposed by caspase cleavage during apoptosis. Myristoylation plays a vital role in membrane targeting and signal transduction in plant responses to environmental stress. Compared to other species that possess a single functional myristoyl-CoA: protein N-myristoyltransferase (NMT) gene copy, human, mouse and cow possess 2 NMT genes, and more than 2 protein isoforms.
