3. If the following polypeptide was digested by trypsin, give the resulting peptides. Glu-Gly-Val-Phe-Ser-Ala-Arg-Ser-Ala-Phe

3. If the following polypeptide was digested by trypsin, give the resulting peptides. 

Glu-Gly-Val-Phe-Ser-Ala-Arg-Ser-Ala-Phe-Lys-Pro-lle-Cys-Lys-Trp-Asp-Val-Met 


4. For the following peptide, predict all the b-and y-ion series (with its m/z), under acidic analysis conditions. 

Ser-Phe-Tyr-Cys-Trp-Ala-Arg 


The first and last entries have been started. Use the residue amu from slide 28 (Mass Spec II). [For the b-ions start at the top, from Ser. For the y-ions, start at the bottom, from Arg.)

    On your internship, you visit the Mass Spectrometry Lab. Mass spectrometry can identify short peptide fragments based on their molecular weights. Your fellow intern Jerry has neglected to label his tubes of amyloid beta peptide 42 after digesting them with some proteases that we learned about in Module 6: pepsin, trypsin, and chymotrypsin. Help him figure out what protease is in each tube. Jerry’s supervisor has the fragments listed in the same order as the original peptide primary sequence, which...

    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
