Protein sequences are customarily 'reconstructed' from sequenced fragments because
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.
