Molecular function

acetyl-CoA:peptide alpha-N-acetyltransferase activity, acetyl-CoA:peptide nalpha-acetyltransferase activity, nalpha-acetyltransferase activity, protein N-terminal acetyltransferase activity

Catalysis of the reaction: acetyl-CoA + peptide = CoA + N-alpha-acetylpeptide. This reaction is the acetylation of the N-terminal amino acid residue of a peptide or protein.

N(alpha)-acetyltransferase activity, NAT activity, amino-terminal amino acid-acetylating enzyme activity, peptide acetyltransferase activity
