RL Submitted (NOV-2012) to the EMBL/GenBank/DDBJ databases.
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|PIRNR:PIRNR006621}.
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000256|ARBA:ARBA00001917,
CC ECO:0000256|PIRNR:PIRNR006621};
CC -!- SIMILARITY: Belongs to the dus family. {ECO:0000256|PIRNR:PIRNR006621}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
