The sequences of the core regions in the relative derivatives of the P srfA promoter (a). The core regions of the P srfA promoter (labeled as P03 in the figure) were changed individually or in combination to the corresponding consensus sequence. The mutant sequences compared to the wild-type sequences of the P03 promoter were represented in bold italic. The fluorescence intensity controlled by the derivatives (b) and SDS-PAGE analysis of the GFP expression (c). The band corresponding to GFP was marked
