Molecular Interactions of the Stromal Subunit PsaC with the PsaA/PsaB Heterodimer
The X-ray crystal structure of cyanobacterial Photosystem I (PS I) has been solved to atomic resolution (PDB entry 1JB0). It provides a structural model for the subunits PsaC, PsaD, and PsaE that comprise the stromal ridge of PS I. Independently, the three-dimensional solution structures of unbound, recombinant PsaC (PDB entry 1K0T) and PsaE (PDB entries 1PSF, 1QP2, and 1GXI) have been solved using NMR spectroscopy.
