Description
 5-Fluoroorotic Acid (5-FOA) is widely used in the field of yeast  molecular genetics. The toxicity of 5-FOA to yeast cells with a  functioning URA3 gene which encodes orotidine-5′-P decarboxylase (OMP  decarboxylase), makes it especially useful for the selection and  identification of mutant yeast strains.  5-FOA is most often applied  with Saccharomyces cerevisiae (URA3), although it has been used in other strains including Schizosaccharomyces pombe (URA4 and URA5), Candida albicans (URA3) and the bacterium E. coli  (pyrF). The use of 5-FOA in the yeast 2-hybrid system allows for the  construction of activation domain hybrid libraries to identify  protein-protein interactions.
