- Assume that the 3 polypeptide strands shown below form a parallel B-sheet. Select amino acids AA1, AA2, and AA3 so that the parallel B-sheet is amphipathic and remains stable. Glu-lle-Asn-AA1-Cys-Val Ser-AA2-GIn-Leu-Lys-Phe Lys-Met-Cys-Leu-AA3-Val O AA1 = Pro, AA2 = Leu, AA3 = lle O AA1 = Val, AA2 = Leu, AA3 = Asn O AA1 = Ala, AA2 = Gly, AA3 = Leu AA1 = Phe, AA2 = Arg, AA3 = Ala O ODraw the structure of this peptide: N-Met-His-Tyr-Leu-Asp-Ser-Arg-Leu-CWhich of the following polypeptides would be most likely to form an a helix? Explain your answer. Cys-Arg-Ala-Gly-Asn-Arg-Lys-Glu-Thr-Tyr-Ile-Val-LeuSer-Glu-Asp-Asn-Phe-Gly-Ala-Pro-Lys-Ser-Ile-Leu-TrpGln-Lys-Ala-Ser-Val-Glu-Met-Ala-Val-Arg-Asn-Ser-Gly β sheets are less likely to form than a helices during the earliest stages of protein folding. Explainwhy this is the case. (hint: think about the hydrogen bonding requirements)
- What is the length in AA’s of the LilP protein? Assume fMet is NOT CLEAVED. Write out the sequence of the polypeptide in AA: use the three letter notation, e.g. Met-Ser-Pro-Amino acids project from each polypeptide backbone in a β-sheet in an alternating fashion (oneabove the plane and the next below the plane – see Fig 3.8B). Consider the following proteinsequence: Leu-Lys-Val-Asp-Ile-Ser-Leu-Arg-Leu-Lys-Ile-Arg-Phe-Glu.a. Is there a pattern to these amino acids? If so, what is it? b. What does this sequence of amino acids mean for the hydrophobicity/hydrophilicity of theresulting β-sheet? c. Can you make a prediction about how the β-sheet will be arranged in higher levels of protein structure? If so, what prediction would you make?A polypeptide is digested with trypsin, and the resulting segments are sequenced: Val-Gly Ala-Ala-Gly-Leu-Trp-Arg Arg-Asp-Pro-Gly-Lue-Met-Val-Leu-Tyr-Ala-Ala-Asp-Glu-Lys And the following fragments are produced by chymotrypsin fragmentation: Ala-Ala-Gly-Leu-Trp Arg-Arg-Asp-Pro-Gly-Leu- Met-Val-Leu-Tyr Ala-Ala-Asp-Glu-Lys-Val-Gly What is the sequence of the whole original polypeptide? (Recall that trypsin cleaves a polypeptide backbone at the C-terminal side of Arg or Lys residues, whereas chymotrypsin cleaves after aromatic amino acid residues).
