Structural highlights
FunctionNMT_YEAST 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. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedN-myristoyltransferase (Nmt) attaches myristate to the N-terminal glycine of many important eukaryotic and viral proteins. It is a target for anti-fungal and anti-viral therapy. We have determined the structure, to 2.9 A resolution, of a ternary complex of Saccharomyces cerevisiae Nmt1p with bound myristoylCoA and peptide substrate analogs. The model reveals structural features that define the enzyme's substrate specificities and regulate the ordered binding and release of substrates and products. A novel catalytic mechanism is proposed involving deprotonation of the N-terminal ammonium of a peptide substrate by the enzyme's C-terminal backbone carboxylate.
