Biological function summary

Dihydroorotate dehydrogenase is involved in establishing the pyrimidine pool necessary for DNA and RNA synthesis. It is a single-component enzyme but its activity supports the function of other enzymes in the pathway such as carbamoyl-phosphate synthetase. The proper regulation of DHODH is integral to cellular proliferation and immune responses. Cells that synthesize nucleotides at high rates such as immune cells and cancer cells heavily depend on its activity.

Pathways

Dihydroorotate dehydrogenase is an important player in the pyrimidine biosynthesis pathway and links to the mitochondrial electron transport chain. Its interaction with ubiquinone underlines its role in energy production connecting it to respiratory complexes. DHODH works alongside proteins such as orotate phosphoribosyltransferase which further transforms orotate to orotidine-5'-monophosphate in pyrimidine biosynthesis. These pathways are vital for maintaining the balance of nucleotide levels impacting processes like DNA replication.
