Structures of the simulated complexes. Interface located modification sites are emphasized by the space filled representation. Each site carries a label denoting the subunit, amino acid type, and its position within the respective chain. A, In Skp1:Met30 complex, Skp1 is shown in magenta and Met30 in cyan. B, Exosome and (C) RNA polymerase II subunits are each shown in different color, while (D) parts instead of individual 33 subunits of 26S proteasome are differently colored: 20S core particle β subunits in cyan and α in blue, and 19S regulatory particle base subunits in magenta and lid in gray.
