Uracil/thymine dehydrogenase (EC 1.17.99.4 uracil oxidase uracil-thymine oxidase uracil dehydrogenase) is an enzyme with system name uracil:acceptor oxidoreductase. This enzyme catalyses the following chemical reaction (1) uracil + H2O + acceptor barbiturate + reduced acceptor (2) thymine + H2O + acceptor 5-methylbarbiturate + reduced acceptorUracil/thymine dehydrogenase forms part of the oxidative pyrimidine-degrading pathway in some microorganisms.
