Accepted name: dihydroorotate dehydrogenase (NADP+)
Reaction: (S)-dihydroorotate + NADP+ = orotate + NADPH + H+
Other name(s): orotate reductase; dihydro-orotic dehydrogenase; L-5,6-dihydro-orotate:NAD+ oxidoreductase; orotate reductase (NADPH)
Systematic name: (S)-dihydroorotate:NADP+ oxidoreductase
Comments: Binds FMN and FAD [2]. Other class 1 dihydroorotate dehydrogenases use either fumarate (EC or NAD+ (EC as electron acceptor. The membrane bound class 2 dihydroorotate dehydrogenase (EC uses quinone as electron acceptor .
