A NONAPEPTIDE that attacks and kills cancer cells has just been recently isolated from a rare fungus. Amino acid analysis of the peptide reveals the following information below: (NOTE: when the sequence is not known, a comma separates the amino acids) Hydrezine Nonapeptide Acid Hydrolysis (aN HC) at 110 C (2) Arg. Gin, (2) Tyr, Gly, Ser, Thr, and Met 2,4-dinitrofluorobenzene DNP-Thr Gin and modified free Peptide 1 (Arg. Thr, Ser) amino acids Cleavoge with Trypsin, then chrometography Peptide 2 (Gly, Tyr, Arg) Met Tripeptide (yenogen bromide Dipeptide Cleavoge with Chymetrypsin, then chromatography Peptide 3 (Arg, Ser, Tyr, Thr) Amino acid Peptide 4 (Gly, Arg, Tyr) When answering the questions below, please use the one-letter code for the amino acid, with NO spaces and symbols between each letter. 1. What is the N-terminal AA residue? 2. What is the C-terminal AA residue? 3. What is the sequence of Peptide 1? 4. What is the sequence of Peptide 4? 5. What is the overall amino acid sequence?
