2. You are in a South American rain forest looking for naturally occuring peptides with potential as drugs. You have a mobile biochemistry lab with common reagents and enzymes, an amino-acid analyzer, gel- filtration and ion-exchange chromatography, and electrophoresis. You also have an Edman Sequenator, but you have contaminated one or more of your reagents, and as a result, you cannot sequence peptides longer than about 12 residues before contaminants obscure the results. While screening extracts from the ovaries of an tropical orchid, you find a peptide with potential as an antiviral. Deduce its amino-acid sequence using the available tools. a) MW by electrophoresis can tell you how big a sequencing problem you are up against. Result: about 4000 b) Amino-acid analysis can help you decide how to fragment the peptide for sequencing: Result: A2C2D2E4FG3HKLMN2P2Q2R4S4T3W c) How many peptides expected from each of these possible cleavage reagents? Cyanogen bromide (C-side of M). Staph. aureus V8 protease (C-side of D and E). • Trypsin (C-side of K and R). . ● d) Cleavage by trypsin followed by gel-filtration chromatography gives the expected 6 products, which you sequence (shown in order of emergence from column): T-1 ETMESSAGEFGR T-2 SQTWALDHSECR T-3 GPQDNK T-4 TCR T-5 NP T-6 R e) Cleavage by Staph. aureus V8 protease followed by gel-filtration chromatography gives the expected 7 products, which you sequence (shown in order of emergence from column): S-1 RSQTWALD S-2 FGRGPQD S-3 NKTCRNP S-4 SSAGE S-5 TME S-6 CRE S-7 HSE Think About It: A. Deduce the primary structure of this polypeptide. B. Why would cyanogen bromide not be a good choice as a cleavage reagent? C. Can you account for the order of elution of trypsin digest peptides from gel-filtration chromatography? D. Predict the order of elution of the tryptic peptides from a cation-exchange column eluted with pH-8.5 buffer and a salt gradient. E. Predict the order of elution of the V8 protease peptides from an anion exchange chromatography column eluted with a pH-6.5 buffer and a salt gradient. F. For both sets of peptides, predict the order of elution from a hydrophobic interaction chromatography
