Figure 4.

Structural variations within fold b.1. Domains (a) d1c5ch2, (b) d1akjd_, and (c) d1pama1 belong to the fold b.1 (Immunoglobulin-like beta-sandwich; 7 strands in 2 sheets greek-key, some members of the fold have additional strands). Domain pair (a) and (b) have Pcli = 4.7 and Zscore = 3.09; domain pair (b) and (c) have Pcli = 4.2 and Zscore = 3.34; and domain pair (a) and (c) have Pcli=-0.5 and Zscore = 0.11. Domains d1c5ch2, d1akjd_, and d1pama1 have 103, 114, and 86 residues, respectively. The helices are colored in green, the strands in red, and the other regions in blue. This and all other structure figures were prepared using Pymol [43].
