Which of the following would be a possible amino acid sequence for an oligopeptide given the experimental data below. a. The amino acid composition is found to be tyr, ile, ala, lys, cys and met and some decomposition products.
b. The peptide has a molecular weight around 700 Da and absorbs at 280 nm.
c. Treatment with carboxypeptidase results in isoleucine and a peptide.
d. First cycle Edmond Degradation yields PTHcystine CNBR treatment yields two tri peptides.
e. Trypsin digestion produces a dipeptide and a tetrapeptide with met on the amino end.
