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 (By
CC similarity). {ECO:0000250|UniProtKB:Q06053,
CC ECO:0000250|UniProtKB:Q9UTH9}.
