Pyrimidine oxygenase
Pyrimidine oxygenase (EC 1.14.99.46, RutA) is an enzyme with systematic name uracil,FMNH2:oxygen oxidoreductase (uracil hydroxylating, ring-opening).[1][2] This enzyme catalyses the following chemical reaction
- (1) uracil + FMNH2 + O2 (Z)-3-ureidoacrylate peracid + FMN
- (2) thymine + FMNH2 + O2 (Z)-2-methylureidoacrylate peracid + FMN
