WebThe redox midpoint potential (Em) of the primary quinone of bacterial reaction centers, Q(A), in native membranes (chromatophores) measured by redox potentiometry is reported to be pH dependent (-60 mV/pH) up to a highly distinctive pKa (9.8 in Rba. sphaeroides) for the reduced state. In contrast, the Em of Q(A) in isolated RCs of Rba. sphaeroides, although … Frédéric Comayras 1 , Colette Jungas, Jérôme Lavergne Affiliation 1 Unité Mixte de Recherche 6191 CNRS-Commissariat à l'Energie Atomique-Aix Marseille II, Département d'Ecophysiologie Végétale et de Microbiologie, Commissariat à l'Energie Atomique Cadarache, 13108 Saint Paul-lez-Durance Cedex, France.
