Pleаse use а blаnk sheet оf paper fоr this prоblem and scan it and upload it right after the exam. For the polypeptide sequence, Tyr-Lys-Asp-Val A. Rewrite the name of this polypeptide using the single letter code (2 points) B. Draw the chemical structure of this polypeptide. (4 points) C. If this polypeptide is treated with trypsin, show the fragmentation site(s) by using a vertical dashed line (|) Tyr-Lys-Asp-Val (2 point) D. Draw the actual chemical structures of the fragmented peptide products. (3 points) E. Here are all the pKa values for this polypeptide except for one. Write the approximate pKa value for the Tyr (side chain). +/-1 would be ok (1 point) N-terminus, pKa: 9.0 Tyr (side chain), pKa: ____ Lys (side chain, pKa: 10.8 Asp (side chain), pKa: 3.71 Val (side chain), pKa: ~50 C-terminus, pKa: 2.1 F. Estimate the rough charge of the following groups and the net charge on the peptide at pH=7.4 based on your numbers above. (7 points) N-terminus Tyr (side chain) Lys (side chain) Asp (side chain) Val (side chain) C-terminus Net charge of the peptide G. Estimate the pI of the dipeptide Lys-Asp [Note only dipeptide is mentioned here. Also you can use the listed PI values] (3 points) H. Write Handerson Hasselbach equation (1 point) and then use it to calculate the accurate charge on the Lysine side chain with pKa= 10.8 at pH of 11 (3 points)
