The following data were obtained from partial cleavage and analysis of a pentadecapeptide. Determine the sequence of the pentadecapeptide. Use three-letter abbreviations in your answer. Please explain thoroughly, step by step.

Trypsin cuts chain on the right(carboxylic acid) side of any basic amino acid ...(lys,arg) .
Chimotrypsin cuts chain on the right(carboxylic acid) side of any aromatic amino acid ...(phe,trp,hys,tyr) .
CnBr cuts chain on the right(carboxylic acid) side of metheonine .
Based on these information , we can predict the sequence . That will be ,

Based on where CNBR and trypsin cut, evaluate the following experimental data and predict the N- and C-terminal amino acids of the parent peptide (peptide before cutting). Enter your answer using the three letter amino acid abbreviations, with a comma in between. For example, if the N-terminal residue is alanine and C-terminal residue is glycine you would write: Ala, Gly. Cleavage with CNBR produced the following peptides: Gly-Ala-Lys-Leu-Pro-Met Phe-Trp-Met Asp-Gly-Arg-Cys-Ala-Gln Cleavage with trypsin: Cys-Ala-Gln Phe-Trp-Met-Gly-Ala-Lys Leu-Pro-Met-Asp-Gly-Arg

anyone can help me with it?
A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence of this decapeptide. Trypsin digestion gave two fragments with multiple residues (not in order): • T1: Ala, Arg, Phe, Gly, Thr, Trp, Tyr • T2: Lys, Met, Val Chymotrypsin digestion gave four fragments with multiple residues (not in order): • CT1: Ala, Phe •...
