The photosynthetic reaction centre from the purple bacterium Rhodopseudomonas viridis.
We first describe the history and methods of membrane protein crystallization, and show how the structure of the photosynthetic reaction centre from the purple bacterium Rhodopseudomonas viridis was solved. The structure of this membrane protein complex is correlated with its function as a light-driven electron pump across the photosynthetic membrane. Finally we draw conclusions on the structur...

متن کاملMicroaerophilic growth and induction of the photosynthetic reaction center in Rhodopseudomonas viridis.
Rhodopseudomonas viridis was grown in liquid culture at 30 degrees C anaerobically in light (generation time, 13 h) and under microaerophilic growth conditions in the dark (generation time, 24 h). The bacterium could be cloned at the same temperature anaerobically in light (1 week) and aerobically in the dark (3 to 4 weeks) if oxygen was limited to 0.1%. Oxygen could not be replaced by dimethyl...
متن کاملFirst glance on the three-dimensional structure of the photosynthetic reaction center from a herbicide-resistant Rhodopseudomonas viridis mutant.
A first model of the three-dimensional structure of the photosynthetic reaction center of the mutant T1 (SerL223----Ala, ArgL217----His) from Rhodopseudomonas viridis, resistant toward the triazine herbicide terbutryn (2-methylthio-4-ethylamino-6-t-butylamino-s-triazine), has been developed from X-ray data measured to a resolution of 2.5 A. The secondary quinone, QB, which in T1 binds better th...
متن کاملRoles of proteins in the electron transfer in the photosynthetic reaction center of Rhodopseudomonas viridis: bacteriopheophytin to ubiquinone
The electron transfer (ET) from bacteriopheophytin (H) to ubiquinone (UQ) in the photosynthetic reaction center (PSRC) of Rhodopseudomonas (Rps.) viridis was studied by ab initio quantum-chemical calculations. The ET from the H in L-region (HL) to menaquinone (MQ) occurs through the super-exchange mechanism using Trp M250 as a bridge, while in the M-region Leu L189 works as a bridge in the ET f...
