WebbThe enzyme has a turnover number based on the flavin content of the order of 1200 2a) The rate of reduction of orotic acid is maximal at about pH 6.5. With excess DPNH the reaction proceeds at a sufficient rate, and orotic acid is nearly quantitatively reduced. WebbOrotic acid (6-Carboxyuracil), a precursor in biosynthesis of pyrimidine nucleotides and RNA, is released from the mitochondrial dihydroorotate dehydrogenase (DHODH) for conversion to UMP by the cytoplasmic UMP synthase enzyme. Orotic acid is a marker for measurement in routine newborn screening for urea cycle disorders. Orotic acid can …
