Fig. 2From: A synthetic promoter system for well-controlled protein expression with different carbon sources in Saccharomyces cerevisiaeCharacterization of the synthetic promoters by core promoter replacement. The normalized fluorescence for constructs with only the core promoter (a) and with UASGAL1 fusion (b). The activities of all synthetic promoters were tested after cultivation with 2% glucose (grey) or galactose (orange) for 24 h. Data are mean ± SD from three biological replicatesBack to article page
