Use the given experimental data to deduce the sequence of an octapeptide that contains the amino acids His, Ala (2 equiv), Val (2 equiv), Ser, Gly, and Pro. Edman degradation cleaves Ala from the octapeptide, and carboxypeptidase forms Gly and a heptapeptide. Partial hydrolysis forms the following fragments: Pro-Val-Gly, His-Val-Pro, Ala, and Ala-Ser-His-Val.
