CC -!- FUNCTION: Catalyzes the synthesis of dihydrouridine, a modified base
CC found in the D-loop of most tRNAs. Specifically modifies U47 in
CC cytoplasmic tRNAs (By similarity). Catalyzes the synthesis of
CC dihydrouridine in some mRNAs, thereby affecting their translation.
CC {ECO:0000256|ARBA:ARBA00033731}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5,6-dihydrouridine in mRNA + NAD(+) = a uridine in mRNA +
