Protein
Dihydroorotate dehydrogenase (quinone), mitochondrial
Organism
Candida albicans (strain SC5314 / ATCC MYA-2876)
Function
In the de novo pyrimidine biosynthesis 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.
Similarity
Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily.
