thymine,2-oxoglutarate:oxygen oxidoreductase (7-hydroxylating)

thymine + 2-oxoglutarate + O2 = 5-hydroxymethyluracil + succinate + CO2 [RN:R01412]

R01412;
(other) R08610 R08611
Reaction

thymine [CPD:C00178];
2-oxoglutarate [CPD:C00026];
O2 [CPD:C00007]

Requires Fe2+ and ascorbate. Also acts on 5-hydroxymethyluracil to oxidize its -CH2OH group first to -CHO and then to -COOH.
