Pyrimidine oxygenase (EC 1.14.99.46 RutA) is an enzyme with system name uracilFMNH2:oxygen oxidoreductase (uracil hydroxylating ring-opening) . This enzyme catalyses the following chemical reaction (1) uracil + FMNH2 + O2 (Z)-3-ureidoacrylate peracid + FMN (2) thymine + FMNH2 + O2 (Z)-2-methylureidoacrylate peracid + FMNIn vitro the product (Z)-3-ureidoacrylate peracid is spontaneously reduced to ureidoacrylate.
