TRNA-dihydrouridine20 synthase (NAD(P)+) (EC 1.3.1.91, Dus2p, tRNA-dihydrouridine synthase 2) is an enzyme with systematic name tRNA-5,6-dihydrouracil20:NAD(P)+ oxidoreductase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- 5,6-dihydrouracil20 in tRNA + NAD(P)+ uracil20 in tRNA + NAD(P)H + H+
This enzyme specifically modifies uracil20 in tRNA.
