PHOTOSYNTHETIC REACTION CENTER MUTANT WITH ALA M260 REPLACED WITH TRP (CHAIN M, A260W)

The structure was published by Mcauley, K.E., Fyfe, P.K., Ridge, J.P., Isaacs, N.W., Cogdell, R.J., and Jones, M.R., in 1999 in a paper entitled "Structural Details of an Interaction between Cardiolipin and an Integral Membrane Protein" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1999.

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