Abstract excerpt

* Reductive catabolism of pyrimidine nucleotides occurs via a three-step pathway in which uracil is degraded to beta-alanine, CO(2) and NH(3) through sequential activities of dihydropyrimidine dehydrogenase (EC 1.3.1.2, PYD1), dihydropyrimidinase (EC 3.5.2.2, PYD2) and beta-ureidopropionase (EC 3.5.1.6, PYD3). * A proposed function of this pathway, in addition to the maintenance of pyrimidine homeostasis, is the...
