ABSTRACT
ßαß super-secondary structures constitute the basic building blocks of (ß/α)8 class of proteins. Despite the success in designing super-secondary structures, till date, there is not a single example of a natural ßαß sequence known to fold in isolation. In this chapter, to address the finding the "needles" in the haystack scenario, we have combined the sequence preferences and structural features of independent ßαß motifs, dictated by natural selection, with rationally derived parameters from a designed ßαß motif adopting stable fold in solution. Guided by this approach, a set of potential ßαß sequences from (ß/α)8/TIM barrels are proposed as likely candidates for autonomously folding based on the assessment of their foldability.
