List the peptides formed when the polypeptide shown above is treated with chymotrypsin. 5. Supposed the peptides resultinf from chymotrypsin treatment are then reacted with cyanogen bromide; list the products
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.
