The rudimentary (r) locus of Drosophila melanogaster encodes the first three enzymes for the de novo synthesis of pyrimidines: carbamyl phosphate synthase (CPSase), aspartyl transcarbamylase (ATCase), and dihydroorotase (DHOase). Revertants of leaky r mutants deficient in CPSase have been recovered.
