1. a. Consider the following sequences, which are pieces of alarger, independently folding polypeptide. Which sequence is morelikely to form an alpha helix, and which is more likely to form abeta-hairpin—a two-stranded antiparallel beta-sheet in which thestrands are separated by a turn?
Sequence A: I F I C T T G P N A T V I CV F V
Sequence B: M D R L M E A M A K L D H LL A E
b. How do the structures of the residues I, V, and Tversus L and M contribute to the conformationalpreferences of these two sequences?
c. Which residues likely form the turn between the stands in thebeta-hairpin? Why are these residues suited for this structure?
