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:0000250|UniProtKB:P33371}.
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-
CC COMP:13887, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:65315, ChEBI:CHEBI:74443;
CC Evidence={ECO:0000250|UniProtKB:P33371};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5,6-dihydrouridine in tRNA + NADP(+) = a uridine in tRNA +
CC H(+) + NADPH; Xref=Rhea:RHEA:23624, Rhea:RHEA-COMP:13339, Rhea:RHEA-
CC COMP:13887, ChEBI:CHEBI:15378, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC ChEBI:CHEBI:65315, ChEBI:CHEBI:74443;
CC Evidence={ECO:0000250|UniProtKB:P33371};
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000250|UniProtKB:P33371};
CC -!- SUBUNIT: Co-immunoprecipitates with DarG in the presence and absence of
CC darT. {ECO:0000269|PubMed:32634279}.
CC -!- SIMILARITY: Belongs to the Dus family. {ECO:0000305}.
