title: Constitutive mutants for orotidine 5 phosphate decarboxylase and dihydroorotic acid dehydrogenase in Saccharomyces cerevisiae.
abstract: A mutant yeast constitutive for synthesis of both dihydroorotic acid dehydrogenase and orotidine 5' phosphate decarboxylase has been isolated. This phenotype is due to a single gene unlinked to any of the five genes of the pyrimidine pathway. This gene, called ppr1, induces the unlinked genes ural and ura3. Non-chromosomal cloned ura3 is also under the control of ppr1.
