Pyrimidine oxygenase

Pyrimidine oxygenase (, RutA) is an enzyme with systematic name ''). This enzyme catalyses the following chemical reaction


 * (1) uracil + FMNH2 + O2 $$\rightleftharpoons$$ (Z)-3-ureidoacrylate peracid + FMN
 * (2) thymine + FMNH2 + O2 $$\rightleftharpoons$$ (Z)-2-methylureidoacrylate peracid + FMN

In vitro the product (Z)-3-ureidoacrylate peracid is spontaneously reduced to ureidoacrylate.
