General annotation (Comments)
| Function | In the de novo pyrimidine biosynthesic pathway, catalyzes the stereospecific oxidation of (S)-dihydroorotate to orotate with reduction of flavin and the transfer of electrons to ubiquinone, which is part of the repiratory chain. Does not use fumarate and NAD as electron acceptors. Ref.1 Ref.3 Ref.4 |
| Catalytic activity | (S)-dihydroorotate + a quinone = orotate + a quinol. |
| Cofactor | Binds 1 FMN per subunit. |
| Pathway | |
| Subcellular location | Mitochondrion inner membrane; Single-pass membrane protein Potential Ref.1. |
| Sequence similarities | Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily. |
| Biophysicochemical properties | Kinetic parameters: KM=257 µM for (S)-dihydroorotate Ref.3 KM=109 µM for decylubiquinone Vmax=2 µmol/min/mg enzyme |
