   Legend:   → Mismatch (orange background)
  - → Gap (green background, '-', border residues have a numbering label)
    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'

molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    GO:0004402    histone acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + histone = CoA + acetyl-histone.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    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:0016573    histone acetylation    The modification of a histone by the addition of an acetyl group.
    GO:0051289    protein homotetramerization    The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.
