1 To determine the structure of the CAR1 URS element, we performed a saturation mutagenesis. Peptichemio arginase Saccharomyces cerevisiae S288C
2 Results of the mutagenic analysis indicated that the CAR1 URS was a 9-base-pair palindromic sequence, 5"-AGCCGCCGA-3". Peptichemio arginase Saccharomyces cerevisiae S288C
3 These sequences were shown to support varying degrees of URS function in the expression vector assay, to bind protein as demonstrated by the gel shift assay, and to compete with a DNA fragment containing the CAR1 URS for protein binding. Peptichemio arginase Saccharomyces cerevisiae S288C
4 These sequences were shown to support varying degrees of URS function in the expression vector assay, to bind protein as demonstrated by the gel shift assay, and to compete with a DNA fragment containing the CAR1 URS for protein binding. Peptichemio arginase Saccharomyces cerevisiae S288C
5 These results indicate that the CAR1 URS element possesses the characteristics of a repressor binding site. Peptichemio arginase Saccharomyces cerevisiae S288C
