DHODH

The protein encoded by this gene catalyzes the fourth enzymatic step, the ubiquinone-mediated oxidation of dihydroorotate to orotate, in de novo pyrimidine biosynthesis. This protein is a mitochondrial protein located on the outer surface of the inner mitochondrial membrane. [provided by RefSeq, Jul 2008]

Dihydroorotate Dehydrogenase (Quinone)

Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor.

Mitochondrion inner membrane

Postaxial acrofacial dysostosis (POADS):
POADS is characterized by severe micrognathia, cleft lip and/or palate, hypoplasia or aplasia of the posterior elements of the limbs, coloboma of the eyelids and supernumerary nipples. POADS is a very rare disorder: only 2 multiplex families, each consisting of 2 affected siblings born to unaffected, nonconsanguineous parents, have been described among a total of around 30 reported cases.

Mitochondrial matrix: 1-10
Helical: 11-30
Mitochondrial intermembrane: 31-395

The uncleaved transit peptide is required for mitochondrial targeting and proper membrane integration.
