R6G retention in an S558Y mutant The flow cytometry-based transport assay was carried out as described under “Experimental Procedures” and legend to Fig. 2. The data represent the median fluorescence value obtained from histograms similar to the ones depicted in Fig. 2. Two experiments were performed with two independently grown cultures of each strain (n = 4). Values are the average of the two median values with standard deviation (S.D.) indicated. AU, arbitrary units.

Strain and pertinent genotype	Median fluorescence	S.D.
	AU
AD1–7 (Δpdr5)	408.21	96.94
JG2005 (AD1–7 + pSS558Y)	389.47	52.94
JG2000 (AD1–7 + pSS607)	6.71	0.59
