Question:

A peptide Q has the following composition by amino acid analysis:

Treatment of Q once with the Edman reagent followed by anhydrous acid gives a new peptide R with the following composition by amino acid analysis:

Treatment of Q and R with the enzyme dipeptidyl aminopeptidase (DPAP) yields a mixture of the following peptides: R DPAP DPAP Arg-Gly, Gln-Ala, Leu-Val, Val-Asp, Gly Ala-Gly, Asp-Gln, Gly-Val, Val-Arg
