To derive a CE describing the Zif268 fold, we defined the backbone using coordinates from the Protein Data Bank (PDB) entry 1ZAA, residues 33–60.
Supporting Information Accession Numbers The Protein Data Bank ( http://www.rcsb.org/pdb ) accession number for the human PIN1 WW domain is 1PIN and for the murine zinc finger Zif268 is 1ZAA; the SMART database ( http://smart.embl-heidelberg.de ) accession number for the WW domain is SM00456.

Worm representation of ZF helix residues (canonical numbering 1–11) are shown for four ZF2 domains: two wild-type Zif268 proteins, 1aay/hrZif268 (gray) and 1zaa (red); and two modified Zif268 proteins, 1llm chain C (yellow) and 1f2i chain K (blue).
Figure 3 shows ZF helices from three of the five structures (1zaa, 1llm, 1f2i chain K) superimposed with hrZif268 ZF2 helix to further illustrate the degree and nature of docking variation exhibited by different ZF domains and characterized by the corresponding IAS values.
