- A peptide with the primary structure Lys-Arg-Pro-Leu-Ile-Asp-Gly-Ala must be synthesized by the methods developed by Merrifield. Calculate the percentage of the peptides synthesized that will be full length and have the correct sequence if the addition of each amino acid residue is 96% efficient. Do the calculation a second time but assume a 99% efficiency for each cycle. full-length peptides with the correct sequence if 96% efficient: full-length peptides with the correct sequence if 99% efficient: % %Identify the primary sequence for the polypeptide that yields these fragments upon treatment: His-met-thr-met-ala-trp; Leu-asn-asp-phe; Val-lys obtained from chymotrypsin Leu-asn-asp-phe-his-met; Ala-trp-val-lys; Thr-met obtained from CNBRdraw the structure of the tripeptife Pro-Ser-Cys as it would appear at physiological PH with its C-terminal amino acid residue protected as its methyl ester
- Consider the peptide Asp-Lys-Phe-Glu-Asn-Tyr-Gln-Val-Cys. In a single beaker, you treat this peptide with 2 proteases. One protease cleaves at the N-terminus of aromatic R groups and the other cleaves at the C-terminus of polar, non-ionizable R groups. Following the enzymatic digestion, you want to separate your peptide fragments so that you can identify them. You choose to separate the fragments using an anion exchange column. Beginning at pH=6 you apply your peptide fragments to the column and you gradually decrease the pH of the column stopping the separation when the pH of the column equals 4. Omitting chemical structures, write the amino acid sequence of the peptide fragments that are produced from this digest. Write the order that these fragments will elute from the column (if at all). (Relevant pKa values are: 2.1, 3.8, 4.3, 8.3, 9.6, 10.1, and 10.5)you have the following peptide Arg-Ile-Pro-Leu-Asp-Lys-Glu The net charge on this peptide at pH 7.0 is ?.
