You have purified a new peptide hormone. To determine its amino acid sequence you have digested the polypeptide with trypsin and in a separate reaction you have cleaved the polypeptide with cyanogen bromide. Cleavage with trypsin yielded 5 peptides that were sequenced by Edman degradation as shown in the following. Ser─Leu Asp─Val─Arg Val─Met─Glu─Lys Ser─Gln─Met─His─Lys Ile─Phe─Met─Leu─Cys─Arg Cleavage with cyanogen bromide yielded 4 peptides that were sequenced by Edman degradation: His─Lys─Ser─Leu Asp─Val─Arg─Val─Met Glu─Lys─Ile─Phe─Met Leu─Cys─Arg─Ser─Gln─Met Determine the sequence of the intact protein.
