Answer #1

For the solution follow here : - 2,4-dintrofluoro benzene is a sangers reagent which binds with the N-terminus of Amino acidsequence is Val - Leu carboxypeptidase cleaves the Cter- minus of last Amino Acid which ist Ala then Glu so the last two amintreatment with DNFB gives Phe treatment with carboxypeptida se with Glu which is the last amino acid in v - Ala so the sequenSo the complete sequence will be Val - (Leu - Lys) - Ala Phe Ala - Glu feel free to ask any questions

    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. Be sure to answer...

    Styles A decapeptide has the following amina acid composition: Arg. Asp, Gly, Leu, Lys, Met, Phe, Ser. Trp, and Val Reacting the native peptide with FDNB and then hydrolyzing released 2.4- dinitrophenylvaline. Brief incubation of the native peptide with carboxypeptidase yielded free Leu. Incubation with cyanogen bromide yielded two fragments: a tetrapeptide with composition Met, Phe, Ser, and Val, and a hexapeptide. The hexapeptide yielded 2.4- dinitrophenylglycine. Proteolytic cleavage by trypsin of the native peptide gave free Leu, a tripeptide,...
