The Electrochemical Proton Gradient and Solute Transport in Rhodopseudo-Monas Sphaeroides
Rhodopseudomonas sphaeroides is a Gram-negative phototrophic bacterium which can grow either aerobically in the dark or anaerobically in the light. The bacteria are surrounded by a cell-envelope ...

Reaction Centers from Rhodopseudomonas Sphaeroides in Reconstituted Phospholipid Vesicles. Structural Properties and Light-Dependent Proton Translocation
Reaction Centers (RC’s) from phototrophic bacteria catalyze light-driven transmembrane electron transfer as a first step in the (cyclic) electron transfer chain of such bacteria (for a review see: Okamura et a...

Chapter
The Lactose Carrier of Escherichia Coli Functionally Incorporated in Rhodopseudomonas Sphaeroides Obeys the Regulatory Conditions of the Phototrophic Bacterium
Regulation of solute transport in Rps. sphaeroides is such that the presence of a proton motive force by itself is not enough for solute transport to take place. In addition linear or cyclic electron transfer is ...
