X-RAY HIGH RESOLUTION STRUCTURE OF THE PHOTOSYNTHETIC REACTION CENTER FROM RB. SPHAEROIDES AT PH 10 IN THE CHARGE-SEPARATED STATE, 2ND DATASET

The structure was published by Koepke, J., Krammer, E.M., Klingen, A.R., Sebban, P., Ullmann, G.M., and Fritzsch, G., in 2007 in a paper entitled "Ph Modulates the Quinone Position in the Photosynthetic Reaction Center from Rhodobacter Sphaeroides in the Neutral and Charge Separated States." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2007.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely REACTION CENTER PROTEIN H CHAIN, REACTION CENTER PROTEIN L CHAIN, and REACTION CENTER PROTEIN M CHAIN.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotrimers.
