One-hybrid assay. (A) Ninety-six AD fusions mated to HIS3 reporter plasmid grown on 75 mM 3-amino triazole (3AT), a competitive inhibitor of the HIS3 gene product. The arrow points to the Stp2-AD fusion. (B) AD fusions mated to mutant versions of a HIS3 reporter plasmid. (C) Sequences used as promoters in one-hybrid assay. Red indicates the motif, and blue indicates mutations.
