Enzyme Information
| 1.3.98.1 |
Dihydroorotate oxidase (fumarate).
based on mapping to UniProt Q4D3W2
(S)-dihydroorotate + fumarate = orotate + succinate.
-!- The reaction, which takes place in the cytosol, is the only redox reaction in the de novo biosynthesis of pyrimidine nucleotides. -!- Molecular oxygen can replace fumarate in vitro. -!- Other class 1 dihydroorotate dehydrogenases use either NAD(+) (EC 1.3.1.14) or NADP(+) (EC 1.3.1.15) as electron acceptor. -!- The membrane bound class 2 dihydroorotate dehydrogenase (EC 1.3.5.2) uses quinone as electron acceptor. -!- Formerly EC 1.3.3.1.
