CRYSTALLOGRAPHIC ANALYSES OF SITE-DIRECTED MUTANTS OF THE PHOTOSYNTHETIC REACTION CENTER FROM RHODOBACTER SPHAEROIDES

The structure was published by Chirino, A.J., Lous, E.J., Huber, M., et al., Paddock, M.L., Feher, G., and Rees, D.C., in 1994 in a paper entitled "Crystallographic analyses of site-directed mutants of the photosynthetic reaction center from Rhodobacter sphaeroides." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 1993.

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.

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.
