Glutamic acid is synthesized by the following reaction sequence. Draw a stepwise mechanism for Steps [1]–[3].
An octapeptide contains the following amino acids: Arg, Glu, His, Ile, Leu, Phe, Tyr, and Val. Carboxypeptidase treatment of the octapeptide forms Phe and a heptapeptide. Treatment of the octapeptide with chymotrypsin forms two tetrapeptides, A and B. Treatment of A with trypsin yields two dipeptides, C and D. Edman degradation cleaves the following amino acids from each peptide: Glu (octapeptide), Glu (A), Ile (B), Glue (C), and Val (D). Partial hydrolysis of tetrapeptide B forms Ile-Leu in addition to other products. Deduce the structure of the octapeptide and fragments A-D.
Give the amino acid sequence of each peptide using the fragments obtained by partial hydrolysis of the peptide with acid.
Name each peptide using both the one-letter and the three-letter abbreviations for the names of the component amino acids.
