   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:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0003676    nucleic acid binding    Interacting selectively and non-covalently with any nucleic acid.
    GO:0008276    protein methyltransferase activity    Catalysis of the transfer of a methyl group (CH3-) to a protein.
    GO:0036009    protein-glutamine N-methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + protein L-glutamine = S-adenosyl-L-homocysteine + protein N-methyl-L-glutamine.
    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:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0018364    peptidyl-glutamine methylation    The addition of a methyl group to a glutamine residue in a protein.
    GO:0006479    protein methylation    The addition of a methyl group to a protein amino acid. A methyl group is derived from methane by the removal of a hydrogen atom.
