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. Specifically modifies U16 in tRNAs.
CC {ECO:0000255|HAMAP-Rule:MF_02043}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5,6-dihydrouridine(16) in tRNA + NADP(+) = H(+) + NADPH +
CC uridine(16) in tRNA; Xref=Rhea:RHEA:53376, Rhea:RHEA-COMP:13543,
