5. Consider the following peptide: His-Ser-Gln-Gly-Thr-Phe-Thr-Ser-Asp-Tyr-Ser-Lys-Tyr-Leu-Asp-Ser-Arg-Arg-Ala-Gin- Asp-Phe-Val-Gln-Trp-Leu-Met-Asn-Thr a. What are the fragments, if it is cleaved by trypsin? b. What are the fragments, if it is cleaved by chymotrypsin? c. What are the fragments, if it is cleaved by pepsin?
Can the peptide Ser-Glu-Pro-Ile-Met-Ala-Pro-Val-Glu-Tyr-Pro-Lys be hydrolyzed by chymotrypsin? our teacher indicates that it can, but i was under the impresion that if proline was the next amino acid, then the reaction would not go.
Complete hydrolysis of an unknown basic decapeptide gives Gly, Ala, Leu, Ile, Phe, Tyr, Glu, Arg, Lys, and Ser. Problem 24-44 ConstantsI Periodic Table Complete hydrolysis of an unknown basic decapeptide gives Gly, Ala, Leu, lle, Phe, Tyr, Glu, Arg, Lys, and Ser. Terminal residue analysis shows that the N terminus is Ala and the C terminus is lle. Incubation of the decapeptide with chymotrypsin gives two tripeptides, A and B, and a tetrapeptide, C. Amino acid analysis shows that...
