Superfamily: Dihydrouridine synthase, C-terminal recognition domain

Dihydrouridine synthase (Dus) is responsible for introducing D (Dihydrouridine) modifications into RNA by the reduction of uridine.

The C-terminal tRNA-binding domain is formed by four parallel helices. This domain is commonly found in Dus-family proteins and is responsible for binding to the substrate tRNA. The role of dihydrouridine in tRNA is predicted to increase conformational flexibility of the tRNA.
