PHOTOSYNTHETIC REACTION CENTER MUTANT WITH TRP M115 REPLACED WITH PHE (CHAIN M, WM115F) PHE M197 REPLACED WITH ARG (CHAIN M, FM197R)

The structure was published by Ridge, J.P., Fyfe, P.K., Mcauley, K.E., et al., Isaacs, N.W., Cogdell, R.J., and Jones, M.R., in 2000 in a paper entitled "An Examination of How Structural Changes Can Affect the Rate of Electron Transfer in a Mutated Bacterial Photoreaction Centre" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2000.

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 H SUBUNIT, PHOTOSYNTHETIC REACTION CENTER L SUBUNIT, and PHOTOSYNTHETIC REACTION CENTER M 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.
