Definition
ChEBI: (S)-dihydroorotic acid is the (S)-enantiomer of dihydroorotic acid that is an intermediate in the metabolism of pyridine. It has a role as a Saccharomyces cerevisiae metabolite, a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a conjugate acid of a (S)-dihydroorotate. It is an enantiomer of a (R)-dihydroorotic acid.
Biochem/physiol Actions
L-Dihydroorotic acid (DHO) serves as a substrate for dihydroorotate dehydrogenase (DHODH), an enzyme in the de novo synthesis of pyrimidine. Inhibition of DHOH by its inhibitors causes a large accumulation of upstream metabolite DHO and a reduction in the uridine levels. Therefore, DHO and uridine can be used as biomarkers for pyrimidine synthesis for the clinical development of DHOH inhibitors.
