TABLE 2.
Reporter plasmids contained the lacZ gene under control of the GAL1 promoter with UASG deleted (pLR1Δ1) (31) or replaced by 6 LexA binding sites (pSH18-18).
Strains MCY1974 (ssn6Δ) and MCY829 (wild type) were transformed with reporters containing 0 or 6 LexA binding sites and plasmids expressing LexA-Nrg1, LexA-Nrg2, or LexA alone (pV43, pV44, or pEG202).
Cultures were grown to mid-log phase in selective SC plus 2% glucose (Hi); glucose-grown cells were also shifted to 0.05% glucose (Lo) for 3 h, as indicated.
β-Galactosidase activity was assayed in permeabilized cells and expressed in Miller units. Values are averages for the results for 4 to 6 transformants. For values >1, standard errors were <15%. Values for LexA alone were comparable in high- and low-glucose conditions.
