'''PHOTOSYNTHETIC REACTION CENTER BLASTOCHLORIS VIRIDIS (ATCC)'''<br />


==Overview==
==PHOTOSYNTHETIC REACTION CENTER BLASTOCHLORIS VIRIDIS (ATCC)==
The structure of the Blastochloris viridis photosynthetic reaction center, has been determined at 100 K by flash-freezing crystals. A data set to 2.2, A resolution provides a well determined model of the wild-type protein. Of, particular interest are the position, occupancy and heterogeneity of the, Q(B)-binding site. Data were also collected from a crystal frozen, immediately after illumination. The data support predominant binding of, Q(B) in the proximal position in both the neutral and charge-separated, states.

Data were also collected from a crystal frozen immediately after illumination. The data support predominant binding of Q(B) in the proximal position in both the neutral and charge-separated states.
