Accepted name: pyrimidine-deoxynucleoside 2′-dioxygenase
Reaction: 2′-deoxyuridine + 2-oxoglutarate + O2 = uridine + succinate + CO2
Other name(s): deoxyuridine 2′-dioxygenase; deoxyuridine 2′-hydroxylase; pyrimidine deoxyribonucleoside 2′-hydroxylase; thymidine 2′-dioxygenase; thymidine 2′-hydroxylase; thymidine 2-oxoglutarate dioxygenase; thymidine dioxygenase
Systematic name: 2′-deoxyuridine,2-oxoglutarate:oxygen oxidoreductase (2′-hydroxylating)
Comments: Requires iron(II) and ascorbate. Also acts on thymidine. cf. EC, pyrimidine-deoxynucleoside 1′-dioxygenase.
