A protein biochemist attempted to determine the amino acid sequence of a decapeptide. The results from the trypsin, chymotrypsin, and cyanogen bromide treatments are shown: ⚫ Trypsin digestion gave two fragments with multiple residues (not in order): • T1: Ala, Arg, Phe, Gly, Thr, Trp, Tyr o T2: Lys, Met, Val Chymotrypsin digestion gave four fragments with multiple residues (not in order): • CT1: Ala, Phe • CT2: Thr, Trp • CT3: Lys, Met, Tyr, Val 。 CT4: Arg, Gly ⚫ Treatment with cyanogen bromide yielded a single amino acid, methionine, and a nonapeptide. What is a possible sequence of the decapeptide? Use three-letter abbreviations in your answer, and add a dash between each residue.

Poly-L-leucine in an organic solvent such as dioxane is a helical, whereas poly-L-isoleucine is not. Why do these amino acids with the same number and kinds of atoms have different helix-forming tendencies? L-isoleucine's methyl group sterically interferes with α-helix formation, whereas L-leucine's methyl group does not interfere. L-isoleucine lacks an NH group that can donate a hydrogen bond to stabilize an a helix, whereas L-leucine has an NH group. L-isoleucine contains a hydrogen-bond acceptor in close proximity to the main chain, whereas L-leucine lacks this group. L-isoleucine's ring structure prevents it from assuming the op value to fit into an a helix, whereas L-isoleucine does not have a ring structure.
