Abstract excerpt
Flash-induced absorption spectroscopy has been used to characterize Rhodobacter capsulatus reaction centers mutated in the secondary quinone acceptor site (Q(B). We compared the wild-type, the L212Glu-L213Asp --> Ala-Ala photosynthetically incompetent double mutant (DM), and two photocompetent re...
