Chain A,B,C,D (YYCN_BACSU | O32293)

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.
	GO:0016746	transferase activity, transferring acyl groups	Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor).
biological process
	GO:0017189	N-terminal peptidyl-alanine acetylation	The acetylation of the N-terminal alanine of proteins; catalyzed by peptide alpha-N-acetyltransferase or other enzymes of this class, such as ribosomal-protein-alanine N-acetyltransferase.
cellular component
	GO:0031248	protein acetyltransferase complex	A complex that catalyzes the transfer of an acetyl group to a protein acceptor molecule.
