Chain A   (Q8A635_BACTN | Q8A635)
molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    GO:0004596    peptide alpha-N-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.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0006474    N-terminal protein amino acid acetylation    The acetylation of the N-terminal amino acid of proteins.
cellular component
    GO:0031248    protein acetyltransferase complex    A complex that catalyzes the transfer of an acetyl group to a protein acceptor molecule.
