Protein

Glycylpeptide N-tetradecanoyltransferase

Gene

NMT1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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. Uncharged amino acids are preferred at position 2 while neutral residues are favored at positions 3 and 4. Ser is present at position 5 in almost all known N-myristoyl proteins and Lys is commonly encountered at postion 6.

Catalytic activityi

Tetradecanoyl-CoA + glycylpeptide = CoA + N-tetradecanoylglycylpeptide.

Enzyme regulationi

Inhibited by diethylpyrocarbonate. Competitively inhibited by S-(2-oxo)pentadecyl-CoA, a non hydrolysable myristoyl-CoA analog, and by SC-58272, a peptidomimetic derived from the N-terminal sequence of a natural substrate.

    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.
