molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    GO:0004343    glucosamine 6-phosphate N-acetyltransferase activity    Catalysis of the reaction: D-glucosamine 6-phosphate + acetyl-CoA = N-acetyl-D-glucosamine 6-phosphate + CoA + H(+).
    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).
