Water transport in intact yeast cells as assessed by fluorescence self-quenching.
Intact yeast cells loaded with 5- and-6-carboxyfluorescein were used to assess water transport. The results were similar to those previously reported for protoplasts assessed by using either fluorescence or light scattering, and the activation energies were 8.0 and 15.1 kcal mol(-1) (33.4 and 63.2 kJ mol(-1)) for a strain overexpressing AQY1 aquaporin and a parental strain, respectively.
