Claims

  1. Plant photosystem I is a supercomplex of a reaction centre and light-harvesting complexes; its 3.4 Å crystal structure revealed 17 protein subunits, 168 chlorophylls, 2 phylloquinones, 3 Fe4S4 clusters and 5 carotenoids.
    "Photosystem I (PSI) is a supercomplex of a reaction centre and light-harvesting complexes. [...] We report the structure of plant PSI at 3.4 A resolution, revealing 17 protein subunits. [...] At this level, 168 chlorophylls (65 assigned with orientations for Q(x) and Q(y) transition dipole moments), 2 phylloquinones, 3 Fe(4)S(4) clusters and 5 carotenoids are described."
