Figure S1. Detailed view of regions along the diagonal of the docking- comparison matrix shown in Figure 1. Pair-wise IAS values are shown as in Figure 1. Scores below 5.0 are in white (not shown). IAS values between domains with a wild-type-docking geometry (see text) in each of the three Zif268 groups are delineated with a heavy dashed line. PDB identifier, chain ID and ZF domain number (as in Table 1) for each complex are indicated at the far left. Amino acid identities for the canonical ZF helix positions -1, 2, 3 and 6 (as in Figure 2), and base identities for the recognized base triplet (e.g. bases 4-6, 4’-6’ for ZF2 in Figure 2) are indicated for each complex.
