Overexpression of Erg11p by the Regulatable GAL1 Promoter Confers Fluconazole Resistance in Saccharomyces cerevisiae

The contribution of the dosage of target enzyme P-450 14α-demethylase (14αDM) to fluconazole resistance in both Candida albicans and Saccharomyces cerevisiae remains unclear. Here, we show that overexpression of Saccharomyces P-450 14αDM in S. cerevisiae, under the control of the regulatable promoter GAL1, results in azole resistance.
