Anаlysis оf the blооd of а cаtatonic football fan revealed large concentrations of a psychotoxic octapeptide. Amino acid analysis of this octapeptide gave the following results: 2 Ala, Arg, Asp, Met, 2 Tyr, Val, NH4+ The following facts were observed: Partial acid hydrolysis of the octapeptide yielded a dipeptide of the structure seen below. Chymotrypsin treatment of the octapeptide yielded two tetrapeptides, each containing an alanine residue. Trypsin treatment of one of the tetrapeptides yielded two dipeptides. Cyanogen bromide treatment of another sample of the same tetrapeptide yielded a tripeptide and free Tyr. End-group analysis of the other tetrapeptide gave Asp. What is the amino acid sequence of this octapeptide? Provide your answer by using the single-letter code of the amino acids.
