EC 2.3.1.88     
Accepted name: peptide α-N-acetyltransferase
Reaction: acetyl-CoA + peptide = CoA + Nα-acetylpeptide
Other name(s): β-endorphin acetyltransferase; peptide acetyltransferase; protein N-terminal acetyltransferase; NAT; Nα-acetyltransferase; amino-terminal amino acid-acetylating enzyme; acetyl-CoA:peptide α-N-acetyltransferase
Systematic name: acetyl-CoA:peptide Nα-acetyltransferase
Comments: Acetylates N-terminal alanine, serine, methionine and glutamate residues in a number of peptides and proteins, including β-endorphin, corticotropins and melanotropin. cf. EC 2.3.1.108 α-tubulin N-acetyltransferase.
