molecular function
    GO:0004156    dihydropteroate synthase activity    Catalysis of the reaction: 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate + 4-aminobenzoate = diphosphate + dihydropteroate.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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:0044237    cellular metabolic process    The chemical reactions and pathways by which individual cells transform chemical substances.
    GO:0046656    folic acid biosynthetic process    The chemical reactions and pathways resulting in the formation of folic acid, pteroylglutamic acid.
    GO:0009396    folic acid-containing compound biosynthetic process    The chemical reactions and pathways resulting in the formation of folic acid and its derivatives.
    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.
    GO:0046654    tetrahydrofolate biosynthetic process    The chemical reactions and pathways resulting in the formation of tetrahydrofolate, 5,6,7,8-tetrahydrofolic acid, a folate derivative bearing additional hydrogens on the pterin group.
