molecular function
    GO:0004150    dihydroneopterin aldolase activity    Catalysis of the reaction: 2-amino-4-hydroxy-6-(D-erythro-1,2,3-trihydroxypropyl)-7,8-dihydropteridine = 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine + glycolaldehyde.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
    GO:0046656    folic acid biosynthetic process    The chemical reactions and pathways resulting in the formation of folic acid, pteroylglutamic acid.
    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: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.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
