ABSTRACT
|
|
|
|
| |
|
|
High resolution x-ray diffraction data from crystals of the Rhodobacter
sphaeroides photosynthetic reaction center (RC) have been collected at cryogenic
temperature in the dark and under illumination, and the structures were refined
at 2.2 and 2.6 angstrom resolution, respectively. In the charge-separated
D+QAQB- state (where D is the primary electron donor (a bacteriochlorophyll
dimer), and QA and QB are the primary and secondary quinone acceptors,
respectively), QB- is located approximately 5 angstroms from the QB position in
the charge-neutral (DQAQB) state, and has undergone a 180 degrees propeller
twist around the isoprene chain. A model based on the difference between the two
structures is proposed to explain the observed kinetics of electron transfer
from QA-QB to QAQB- and the relative binding affinities of the different
ubiquinone species in the QB pocket. In addition, several water channels
(putative proton pathways) leading from the QB pocket to the surface of the RC
were delineated, one of which leads directly to the membrane surface.

Fig. 4. Superposition of previously reported positions of
ubiquinone in the Q[B] binding pocket [see also (4)]. PDB
(Protein Data^ Bank, Brookhaven) entries and color code: 1PCR,
Ermler et al. (8), yellow; 2RCR, Chang et al. (6), dark blue;
1YST, Arnoux et al. (7), green; 4RCR, Allen et al. (5), red;
present model of the dark structure, light blue. Superposition
was performed^ by the method of Kabsch (52). Side chain residues
from the current dark structure are indicated. Oxygen, nitrogen,
and carbon atoms are colored red, blue, and gray, respectively.

Figure 5.
Fig. 5. Water channels P1 and P2 observed in the dark RC
structure leading from the Q[B] pocket to the surface of the
protein on the^ cytoplasmic side of the RC. The coloring scheme
is: H subunit (green), L subunit (yellow), M subunit (blue),
water molecules (red), bacteriochlorophylls (green), and
bacteriopheophytin (purple). Q[A] and Q[B] are colored
orange-red, while the nonheme iron is rust-colored. The
positions of the quinone tails past carbon C16 are less well
defined because of poor electron density. The approximate
location of the membrane is indicated by the shaded region. The
details of the P1 and P2 pathways are shown in Fig. 6, A and B.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
