A mixture of the following amino acids (glu, leu, val, arg, ser, phe) was obtained upon complete hydrolysis of a hexapeptide. a. Edman’s reagent releases leucine b. Hexapeptide with carboxypeptidase releases serine. c. Hexapeptide with trypsin forms a tripeptide A with leucine at the N terminal and tripeptide B with valine at the N terminal. d. Tripeptide A with carboxypeptidase releases arginine and a dipeptide with glutamic acid at C terminal. e. Tripeptide B with chymotrypsin form releases serine and another dipeptide. Give: 1. the amino acid sequence of tripeptide A and B. 2. the amino acid sequence in the above hexapeptide.
