molecular function
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0003674    molecular_function    Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
    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:0006760    folic acid-containing compound metabolic process    The chemical reactions and pathways involving a folic acid-containing compound, i.e. any of a group of heterocyclic compounds based on the pteroic acid skeleton conjugated with one or more L-glutamic acid or L-glutamate units.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0042558    pteridine-containing compound metabolic process    The chemical reactions and pathways involving any compound containing pteridine (pyrazino(2,3-dipyrimidine)), e.g. pteroic acid, xanthopterin and folic acid.
