You have a peptide whose sequence is secretly known, that you want to analyze. The peptide sequence is D-M-K-T-L-A-R-S-M-E-I-D-Q You have three reagents that cleave polypeptides, CNBr, chymotrypsin, and trypsin into smaller peptides. If you could purify these peptides and sequence them by Edman, but only get four amino acids. 1) what end of the protein does the Edman reaction cleave residues from? n-terminus or c-terminus 2) what are all the Edman sequences (up to 4 amino acids) of the...
