In enzymology, a glycylpeptide N-tetradecanoyltransferase (EC 2.3.1.97) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are tetradecanoyl-CoA and glycylpeptide, whereas its two products are CoA and N-tetradecanoylglycylpeptide. It participates in the N-Myristoylation of proteins, and in vertebrates there are two isoenzymes NMT1 and NMT2.
Besides tetradecanoyl-CoA, this enzyme is also capable of using modified versions of this substrate. [1] In human retina, an even wider range of fatty acids, including 14:1 n–9, 14:2n–6, and 12:0, are accepted by the enzyme and grafted onto guanylate cyclase activators. [2] This is mainly a result of a special set of fatty-acid-CoA substrates available in the retina. [3]
This enzyme belongs to the family of transferases, specifically those N-acyltransferases transferring groups other than aminoacyl groups (cd04301). The systematic name of this enzyme class is tetradecanoyl-CoA:glycylpeptide N-tetradecanoyltransferase. Other names in common use include peptide N-myristoyltransferase (NMT), myristoyl-CoA-protein N-myristoyltransferase, myristoyl-coenzyme A:protein N-myristoyl transferase, myristoylating enzymes, and protein N-myristoyltransferase.
As of late 2007, 9 structures have been solved for this class of enzymes, with PDB accession codes 1IIC, 1IID, 1IYK, 1IYL, 1RXT, 2NMT, 2P6E, 2P6F, and 2P6G.
The enzyme folds into two domains, each with a double EF-hand arrangement.
Myristoylation is a lipidation modification where a myristoyl group, derived from myristic acid, is covalently attached by an amide bond to the alpha-amino group of an N-terminal glycine residue. Myristic acid is a 14-carbon saturated fatty acid (14:0) with the systematic name of n-tetradecanoic acid. This modification can be added either co-translationally or post-translationally. N-myristoyltransferase (NMT) catalyzes the myristic acid addition reaction in the cytoplasm of cells. This lipidation event is the most common type of fatty acylation and is present in many organisms, including animals, plants, fungi, protozoans and viruses. Myristoylation allows for weak protein–protein and protein–lipid interactions and plays an essential role in membrane targeting, protein–protein interactions and functions widely in a variety of signal transduction pathways.
The long chain fatty acyl-CoA ligase is an enzyme of the ligase family that activates the oxidation of complex fatty acids. Long chain fatty acyl-CoA synthetase catalyzes the formation of fatty acyl-CoA by a two-step process proceeding through an adenylated intermediate. The enzyme catalyzes the following reaction,
Carnitine palmitoyltransferase I (CPT1) also known as carnitine acyltransferase I, CPTI, CAT1, CoA:carnitine acyl transferase (CCAT), or palmitoylCoA transferase I, is a mitochondrial enzyme responsible for the formation of acyl carnitines by catalyzing the transfer of the acyl group of a long-chain fatty acyl-CoA from coenzyme A to l-carnitine. The product is often palmitoylcarnitine, but other fatty acids may also be substrates. It is part of a family of enzymes called carnitine acyltransferases. This "preparation" allows for subsequent movement of the acyl carnitine from the cytosol into the intermembrane space of mitochondria.
Glycylpeptide N-tetradecanoyltransferase 2 known also as N-myristoyltransferase, is an enzyme that in humans is encoded by the NMT2 gene.

Sterol O-acyltransferase is an intracellular protein located in the endoplasmic reticulum that forms cholesteryl esters from cholesterol.
Glycylpeptide N-tetradecanoyltransferase 1 also known as myristoyl-CoA:protein N-myristoyltransferase 1 (NMT-1) is an enzyme that in humans is encoded by the NMT1 gene. It belongs to the protein N-terminal methyltransferase and glycylpeptide N-tetradecanoyltransferase family of enzymes.
Glycine-N-acyltransferase, also known as GLYAT, is an enzyme which in humans is encoded by the GLYAT gene.
1-Lysophosphatidylcholines are a class of phospholipids that are intermediates in the metabolism of lipids. They result from the hydrolysis of an acyl group from the sn-1 position of phosphatidylcholine. They are also called 2-acyl-sn-glycero-3-phosphocholines. The synthesis of phosphatidylcholines with specific fatty acids occurs through the synthesis of 1-lysoPC. The formation of various other lipids generates 1-lysoPC as a by-product.
Ghrelin O-acyltransferase also known as membrane bound O-acyltransferase domain containing 4 is an enzyme that in humans is encoded by the MBOAT4 gene. It is homologous to other membrane-bound O-acyltransferases. It is a polytopic membrane protein what takes part in lipid signaling reactions. It is the only known enzyme that catalyzes the acylation of ghrelin through the transfer of n-octanoic acid to ghrelin Ser3. Ghrelin O-acyltransferase function is essential in regulation of appetite and the release of growth hormone. Ghrelin O-acyltransferase is a target for scientific research due to promising applications in the treatment of diabetes, eating disorders, and metabolic diseases.
