Characterization of AqpZ-mediated water permeability in Synechocystis cells subjected to hyperosmotic stress. (A and B) Time course of light scattering of Synechocystis WT and ΔaqpZ cells moved to BG11 medium containing 1.0 M sorbitol (A) or 0.5 M NaCl (B). (C and D) Pf of WT and ΔaqpZ cells exposed to various concentrations of sorbitol (C) or NaCl (D) in BG11 medium. (E to H) The same experiments shown in panels A to D were repeated with cells incubated in 80 mM HEPES-MES (pH 8.0) instead of BG11 medium. A.U., absorbance units.
