Figure 4
Crystal packing and structural details of C-PC crystallized in the rhombohedral space group R32 (data set 10, Supplementary Table S3). (a) The unit-cell content is depicted as an overlay in the crystal-packing context. (b) B-factor plot as a function of position in the individual heterodimeric C-PC molecules. (c) Each heterodimeric C-PC molecule harbours three attached phycocyanobilin ligands (yellow). (d) The dodecameric ring structure with the top ring in cartoon representation and the bottom ring as a surface (grey). |
