FIG. 5.

Effects of BM2 on Rh6G uptake and efflux. (A) Rh6G uptake by S. cerevisiae AD/PDR5+ and AD/PDR5− cells was measured in the presence or the absence of 10 μM BM2, as described in Materials and Methods. (B) Rh6G efflux from S. cerevisiae AD/PDR5+ cells was measured in the presence or the absence of 0.2% glucose, as described in Materials and Methods. Glucose-dependent efflux is defined as the Rh6G efflux detected in the presence of glucose minus the efflux detected in the absence of glucose.
