STRUCTURE OF THE PHOTOCHEMICAL REACTION CENTER OF A SPHEROIDENE CONTAINING PURPLE BACTERIUM, RHODOBACTER SPHAEROIDES Y, AT 3 ANGSTROMS RESOLUTION

The structure was published by Arnoux, B., Gaucher, J.F., Ducruix, A., and Reiss-Husson, F., in 1995 in a paper entitled "Structure of the photochemical reaction centre of a spheroidene-containing purple-bacterium, Rhodobacter sphaeroides Y, at 3 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 1994.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely PHOTOSYNTHETIC REACTION CENTER (L SUBUNIT), PHOTOSYNTHETIC REACTION CENTER (M SUBUNIT), and PHOTOSYNTHETIC REACTION CENTER (H SUBUNIT).

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.
