PHOTOSYNTHETIC REACTION CENTER MUTANT WITH ALA M149 REPLACED WITH TRP (CHAIN M, AM149W)

The structure was published by Fyfe, P.K., Potter, J.A., Cheng, J., Williams, C.M., Watson, A.J., and Jones, M.R., in 2007 in a paper entitled "Structural Responses to Cavity-Creating Mutations in an Integral Membrane Protein." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 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.
