Dihidroorotat dehidrogenaza (fumarat) (EC 1.3.98.1, DHOdehaza (nespecifična), dihidroorotat dehidrogenaza (nespecifična), dihidoorotna kiselina dehidrogenaza (nespecifična), DHOD (nespecifična), DHODaza (nespecifična), dihidroorotatna oksidaza, pyr4 (gen)) je enzim sa sistematskim imenom (S)-dihidroorotat:fumarat oksidoreduktaza.[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (S)-dihidroorotat + fumarat orotat + sukcinat
Ovaj enzim vezuje FMN. Reakcija, koja se odvija u citozolu, je jedina redoks reakcija u de novo biosinteza pirimidinskih nukleotida.
