context_page_description: In enzymology, a dihydropyrimidinase is an enzyme that catalyzes the chemical reaction
  5,6-dihydrouracil + H₂O 3-ureidopropanoate
  Thus, the two substrates of this enzyme are 5,6-dihydrouracil and H₂O, whereas its product is 3-ureidopropanoate.
  This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. The systematic name of this enzyme class is 5,6-dihydropyrimidine amidohydrolase. Other names in common use include hydantoinase, hydropyrimidine hydrase, hydantoin peptidase, pyrimidine hydrase, and D-hydantoinase. This enzyme participates in 3 metabolic pathways: pyrimidine metabolism, beta-alanine metabolism, and pantothenate and coa biosynthesis.
