Proton Uptake of Rhodobacter capsulatus Reaction Center Mutants Modified in the Primary Quinone Environment

Flash-induced absorbance spectroscopy was used to analyze the proton uptake and electron transfer properties of photosynthetic reaction centers (RC) of Rhodobacter capsulatus that have been genetically modified near the primary quinone electron acceptor (QA). M246Ala and M247Ala, which are symmetry-...
