'''Crystal Structure of Pf-PCP(1-204)-C'''<br />


==Overview==
==Crystal Structure of Pf-PCP(1-204)-C==
Certain sequences, known as chameleon sequences, take both alpha- and, beta-conformations in natural proteins. We demonstrate that a wild, chameleon sequence fused to the C-terminal alpha-helix or beta-sheet in, foreign stable proteins from hyperthermophiles forms the same conformation, as the host secondary structure. However, no secondary structural, formation is observed when the sequence is attached to the outside of the, secondary structure. These results indicate that this sequence inherently, possesses an ability to make either alpha- or beta-conformation, depending, on the sequentially neighboring secondary structure if little other, nonlocal interaction occurs. Thus, chameleon sequences take on a satellite, state through contagion by the power of a secondary structure. We propose, this "conformational contagion" as a new nonlocal determinant factor in, protein structure and misfolding related to protein conformational, diseases. Proteins 2007.

== Publication Abstract from PubMed ==
Certain sequences, known as chameleon sequences, take both alpha- and beta-conformations in natural proteins. We demonstrate that a wild chameleon sequence fused to the C-terminal alpha-helix or beta-sheet in foreign stable proteins from hyperthermophiles forms the same conformation as the host secondary structure. However, no secondary structural formation is observed when the sequence is attached to the outside of the secondary structure. These results indicate that this sequence inherently possesses an ability to make either alpha- or beta-conformation, depending on the sequentially neighboring secondary structure if little other nonlocal interaction occurs. Thus, chameleon sequences take on a satellite state through contagion by the power of a secondary structure. We propose this "conformational contagion" as a new nonlocal determinant factor in protein structure and misfolding related to protein conformational diseases.
