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.
If you sketch the titration curve for the following protein (Ser−Tyr−Ser−Met−Glu−His−Phe−Arg−Trp−Gly−Lys−Pro−Val), near what pH values would you expect the curve to exhibit inflections?
