TRNA-dihydrouridine20a/20b synthase (NAD(P)+) (EC 1.3.1.90, Dus4p) is an enzyme with systematic name tRNA-5,6-dihydrouracil20a/20b:NAD(P)+ oxidoreductase.[1] This enzyme catalyses the following chemical reaction
- (1) 5,6-dihydrouracil20a in tRNA + NAD(P)+ uracil20a in tRNA + NAD(P)H + H+
- (2) 5,6-dihydrouracil20b in tRNA + NAD(P)+ uracil20b in tRNA + NAD(P)H + H+
A flavoenzyme. The enzyme specifically modifies uracil20a and uracil20b in tRNA.
