Enzyme Information

2.3.1.97

Glycylpeptide N-tetradecanoyltransferase.

based on mapping to UniProt P30419

Tetradecanoyl-CoA + an N-terminal-glycyl-[protein] = CoA + an N-terminal- N-tetradecanoylglycyl-[protein].

-!- The enzyme catalyzes 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.
