Reduction of cytochromes b6 and f in isolated plastoquinol-plastocyanin oxidoreductase driven by photochemical reaction centers from Rhodopseudomonas sphaeroides.

Abstract

Photochemical reaction centers isolated from the bacterium Rhodopseudomonas sphaeroides are able to donate electrons to cytochromes b6 and f in the plastoquinol,-platocyanin oxidoreductase isolated from spinach chloroplasts. The reduction reactions occur only after the second single turnover flash, in a reaction which is sensitive to inhibitors of the… (More)
