5-fluoro Orotic acid (5-FOA) is used to detect URA3 gene expression in yeast molecular genetic constructs.{28301} Yeast with an active URA3 gene, which encodes orotine-5'-monophosphate decarboxylase, converts 5-FOA to fluorodeoxyuridine, which is toxic to cells. Resistant strains of yeast that carry a mutation in the URA3 gene grow in the presence of 5-FOA if the media is supplemented with uracil.
