A number of key PDB files ( http://www.rcsb.org ) should be on the list for those interested in photosystem reaction centres:
3ARC.pdb (Umena et al., 2011) for PSII,
1Q90.pdb (Stroebel et al., 2003) for Cytochrome b6f,
1JB0.pdb (Jordan et al. 2001) for PSI,
2o01.pdb (Amunts et al., 2007) for LHCI-PSI,
1Qo1.pdb for ATP synthase (Walker & co-workers).

Use the Swiss PDB viewer or PyMol to enjoy.
