Effect of ionophores A23187 and nigericin on the light-induced redistribution of Mg2+, K+ and H+ across the thylakoid membrane.

Abstract

Passive redistributions of Mg2+ and K+ ions across the thylakoid membranes, occurring in association with the light-driven electrogenic influx of hydrogen ions have been examined in suspensions of broken spinach chloroplasts under a variety of conditions. (i) In accord with results of Hind el al. (Proc. Natl. Acad. Sci. U.S. (1974) 71, 1484), it was found… (More)
