Evaluation of a Possible Pathway for Ubiquinone Shutteling in the Photosynthetic Unit of the Purple Bacteria Rhodospirillum rubrum — •Andrew Aird1, Carsten Tietz1, Jörg Wrachtrup1, and Klaus Schulten2 — 13.

The core complex of the photosynthetic unit of the purple bacteria Rhodospirillum rubrum plays a cruical role in the conversion of light into chemical energy. In the reaction center a Quinone molecule functions as electron carrier to transport the electrons, created in the first step of photosynthesis, from the inside of the core complex to the Cytochrome bc1-complex. The exact pathway of the Quinone molecule is still unknown. Molecular Dynamics Simulations of the shutteling of the Quinone molecule were performed to see if the molecule is able to diffuse through the closed LH1 ring.
