Photosynthetic organisms that do not evolve oxygen are found in four of the 24 phyla of
bacteria: Proteobacteria (purple bacteria), Chloroflexi (green, non-sulfur bacteria), Chlorobi …

Photosynthetic reaction centers from anoxygenic bacteria are the best-characterized
membrane protein complexes. This chapter compares over 50 X-ray crystal structures of …

Absorption of the energy of a photon in the RC is followed by rapid, efficient electron transfer
from a primary donor along a chain of acceptors leading across the photosynthetic …

The structural, functional, and evolutionary relationships between photosystem II and the
purple nonsulfur bacterial reaction center have been recognized for several years. These …

Photosynthetic reaction centers from purple bacteria are the best known membrane protein
complexes. In this review, X-ray crystal structures of the reaction centers from …

Electron transfer between the photosynthetic reaction center and the cytochrome bc 1
complexes is often mediated by a high redox potential soluble cytochrome. In purple non …

The light driven electron transfer reactions of photosynthesis are best characterized in the
reaction centers of purple nonsulfur bacteria such as Rhodobacter sphaeroides. These …

Publisher Summary The high level of diversity among photosynthetic bacteria, including
cyanobacteria, stands in contrast to the relative uniformity found among the chloroplasts of …

The purple bacterial reaction center has made major contributions to our understanding of
photosynthetic energy transduction and biological electron transfer. A major element in this …

In a light-driven electron transfer reaction, the RC stabilizes the separation of charged
species across the photosynthetic membrane. It thereby catalyzes the twoelectron reduction …
