molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    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.
