Chain A,B,C,D   (THYX_THEMA | Q9WYT0)
molecular function
    GO:0050660    flavin adenine dinucleotide binding    Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0050797    thymidylate synthase (FAD) activity    Catalysis of the reaction: 5,10-methylenetetrahydrofolate + dUMP + NADPH + H+ = dTMP + tetrahydrofolate + NADP+.
    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:0006231    dTMP biosynthetic process    The chemical reactions and pathways resulting in the formation of dTMP, deoxyribosylthymine monophosphate (2'-deoxyribosylthymine 5'-phosphate).
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0009165    nucleotide biosynthetic process    The chemical reactions and pathways resulting in the formation of nucleotides, any nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic-nucleotides (nucleoside cyclic phosphates).
