Effect of Sulfhydryl Reagents on K+ Efflux from Rose Cells

Relationship to Ultraviolet-Stimulated Efflux

Abstract

N-Ethylmaleimide causes a rapid efflux of K+ from suspension-cultured cells of Rosa damascena. This efflux shows many characteristics of the ultraviolet-induced efflux of K+, including the appearance of HCO3 together with the K+ and inhibition by respiratory inhibitors. Cysteine inhibits the ultraviolet-induced efflux of K+. These results are interpreted to mean that ultraviolet induces K+ efflux through an alteration of sulfhydryl residues.
