CC -!- FUNCTION: Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified
CC base found in the D-loop of most tRNAs, via the reduction of the C5-C6
CC double bond in target uridines. {ECO:0000256|ARBA:ARBA00002790,
CC ECO:0000256|PIRNR:PIRNR006621}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5,6-dihydrouridine in tRNA + NAD(+) = a uridine in tRNA +
CC H(+) + NADH; Xref=Rhea:RHEA:54452, Rhea:RHEA-COMP:13339, Rhea:RHEA-
