An octapeptide contains the following amino acids: Met, Thr, Cys, Asp, Phe, Arg, Glu, Gln. Carboxypeptidase treatment of the octapeptide forms Asp and a heptapeptide. Treatment of the octapeptide with Chymotrypsin forms forms two tetrapeptides, A and B. Treatment of A with Trypsin yields two dipeptides, C and D. Edman degradation cleaves the following amino acids from each peptide: Cys (octapeptide), Cys (A), Gln (B), Cys (C), Glu(D). Partial hydrolysis of tetrapeptide B forms Gln-Thr in addition to other products....

Deduce the sequence of a heptapeptide that contains the amino
acids Met, Gln, Phe, Leu, Cys, Val, and Arg, from the following
experimental data. Edman degradation cleaves Cys from the
heptapeptide, and carboxypeptidase forms Gln and a hexapeptide.
Treatment of the heptapeptide with chymotrypsin forms a hexapeptide
and a single amino acid. Treatment of the heptapeptide with trypsin
forms a pentapeptide and a dipeptide. Partial hydrolysis forms Gln,
Cys, Phe, and the tripeptides Leu-Met-Val and Met-Val-Arg.
