A particular peptide has the following amino acid composition of (Lys, Phe, Met, Asp and Thr). The following experimental observations have been made. Trypsin yields 2 peptides with composition (Lys, Met, Asp) and (Thr, Phe) Cyanogen bromide cleavage gives 2 peptides with composition (Met, Asp) and (Lys, Thr, Phe). Chymotrypsin give 2 peptides with composition (Lys, Met, Phe, Asp) and (Thr). Trypsin cleaves at the C-terminus of Arg and Lys. Chymotrypsin cleaves at the C-terminus of aromatic residues. Cyanogen bromide cleaves at the C-terminus of Met. What is the amino acid sequence
