The use of proline as a nitrogen source causes hypersensitivity to 5-fluoro-orotic acid (5FOA) and allows up to 40-fold less of this drug to be used to select for the loss of URA3 function in Saccharomyces cerevisiae. 5FOA hypersensitivity is presumably due to the absence of nitrogen catabolite repression when proline is substituted for (NH4)2SO4 as a nitrogen source. There are two constraints to the use of the proline-5FOA combination: (1) S288c genetic background strains are hypersensitive to 5FOA when grown in proline as a nitrogen source but at least one other genetic background is resistant to low levels of 5FOA under these conditions. (2) The addition of some nutritional supplements confers phenotypic resistance to the 5FOA-proline combination.
