>TIGR00737 nifR3_yhdG putative TIM-barrel protein, nifR3 family; InterPro: IPR004652 This family represents one branch of COG0042 from COG (Predicted TIM-barrel enzymes, possibly dehydrogenases, nifR3 family) and includes NifR3 itself, from Rhodobacter capsulatus. Members of this family catalyse the reduction of the 5,6-double bond of a uridine residue on tRNA. Dihydrouridine modification of tRNA is widely observed in prokaryotes and eukaryotes , and also in some archaea. Most dihydrouridines are found in the D loop of t-RNAs. The role of dihydrouridine in tRNA is currently unknown, but may increase conformational flexibility of the tRNA. ; GO: 0016491 oxidoreductase activity, 0050660 FAD binding, 0008033 tRNA processing.
