Surface area values are calculated from a Voronoi decomposition using the program by Gerstein and Chothia (1996). Left and right domains refer to the subunits as written in the letter pairs. The residue ranges of the domains are listed in Supplementary Table 1. Low values are shaded pink and high values are shaded green.
