Highly stable sequences and structures for the SAP protein conformation for the informational (A) and physics-based (B) scoring functions. Residue frequency distribution in such sequences is shown as a sequence logo (left), and positions with more than 2 bits of Shannon information are mapped onto the structure of SAP with equivalent colors (right, non-informative positions shown in white).
