Porcine dynorphin is a neuropeptide having 17 amino acid residues. Its structure is shown below. Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Ile-Arg-Pro-Lys-Leu-Lys-Trp-Asp-Asn-Gln 8. How does trypsin catalyze the hydrolysis of peptides? You can answer this question by identifying the amino acids involved and whether the hydrolysis is at their amino side or the carboxyl side or if particular amino acids end up at the N-teminal end or at the C-terminal end. 9. List down the different fragments that would result if dynorphin were cleaved by trypsin. 10. How does chymotrypsin catalyze the hydrolysis of peptides?

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?
