Abstract excerpt

The mechanisms of proton conduction to the reduced secondary quinone in bacterial reaction centers were studied in wild-type and genetically modified reaction centers from Rhodobacter capsulatus. In the L212-213AA double mutant (L212Glu----Ala, L213Asp----Ala), reaction center function is severel...
