(4 points) You have an oligopeptide with an unknown amino acid sequence and perform the following experiments: - Complete hydrolysis by 6MHCl at 110C followed by amino acid analysis indicated that the following amino acids are present: - Met, Glu, Lys, Phe, Asn, Asp in a 2:1:1:1:1:1 mole ratio. - Treatment with cyanogen bromide gave three fragments: - one fragment containing a dipeptide of Glu and Met in a 1:1 mole ratio - one fragment containing a tetrapeptide with Lys, Phe, Asn, Met in a 1:1:1:1 mole ratio one fragment containing a single amino acid, Asp. - Cleavage of the oligopeptide with trypsin gave two fragments: one fragment containing a tetrapeptide of Met, Glu, Lys, Phe in 1:1:1:1 mole ratio - one fragment containing a tripeptide of Asn, Met, and Asp in a 1:1:1 mole ratio. - Cleavage of the oligopeptide with chymotrypsin gave two fragments: one fragment containing a tripeptide of Met, Glu, and Phe in a 1:1:1 mole ratio - one fragment containing a tetrapeptide of Asn, Met, Asp, and Lys in a 1:1:1:1 mole ratio. these data, determine the amino acid sequence of the oligopeptide
