Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Adds a myristoyl group to the N-terminal glycine residue of certain cellular proteins. Substrate specificity requires an N-terminal glycine in the nascent polypeptide substrates. Ser is present at position 5 in almost all known N-myristoyl proteins and Lys is commonly encountered at postion 6. Basic residues are preferred at positions 7 and 8. Ref.1 Ref.3 Ref.4
Catalytic activity	Tetradecanoyl-CoA + glycylpeptide = CoA + N-tetradecanoylglycylpeptide.
Enzyme regulation	Competitively inhibited by SC-58272, a peptidomimetic derived from the N-terminal sequence of a natural substrate.
Subunit structure	Monomer.
Subcellular location	Cytoplasm.
Miscellaneous	Has an ordered Bi-Bi kinetic mechanism, with myristoyl-CoA binding taking place prior to peptide binding and CoA release occurring before acylated peptide release. Cooperative interactions between the acyl-CoA and peptide binding sites of NMT contribute to its extraordinary chain-length specificity.
Sequence similarities	Belongs to the NMT family.
