IUBMB Enzyme Nomenclature


Accepted name: glycylpeptide N-tetradecanoyltransferase

Reaction: tetradecanoyl-CoA + an N-terminal-glycyl-[protein] = CoA + an N-terminal-N-tetradecanoylglycyl-[protein]

Glossary: tetradecanoyl-CoA = myristoyl-CoA

Other name(s): NMT (gene name); peptide N-myristoyltransferase; myristoyl-CoA-protein N-myristoyltransferase; myristoyl-coenzyme A:protein N-myristoyl transferase; myristoylating enzymes; protein N-myristoyltransferase; tetradecanoyl-CoA:glycylpeptide N-tetradecanoyltransferase

Systematic name: tetradecanoyl-CoA:N-terminal-glycine-[protein] N-tetradecanoyltransferase

Comments: The enzyme catalyses the transfer of myristic acid from myristoyl-CoA to the amino group of the N-terminal glycine residue in a variety of eukaryotic proteins. It uses an ordered Bi Bi reaction in which myristoyl-CoA binds to the enzyme prior to the binding of the peptide substrate, and CoA release precedes the release of the myristoylated peptide. The enzyme from yeast is profoundly affected by amino acids further from the N-terminus, and is particularly stimulated by a serine residue at position 5.
