Accepted name: uridine-5′-phosphate dioxygenase
Reaction: UMP + 2-oxoglutarate + O2 = 5′-dehydrouridine + succinate + CO2 + phosphate

Glossary: 5′-dehydrouridine = uridine-5′-aldehyde
Other name(s): lipL (gene name)
Systematic name: UMP,2-oxoglutarate:oxygen oxidoreductase
Comments: The enzyme catalyses a net dephosphorylation and oxidation of UMP to generate 5′-dehydrouridine, the first intermediate in the biosynthesis of the unusual aminoribosyl moiety found in several C7-furanosyl nucleosides such as A-90289s, caprazamycins, liposidomycins, muraymycins and FR-900453. Requires Fe2+.
