A form of the polypetide hormone angiotensin II has the amino acid composition ( ASP, ARG, ILE, MET, PHE, PRO, TYR, VAL). The following observations are made. A. Trysin yields a dipeptide containing ASP and ARG and a hexapeptide with all the rest. B. Cyanogen Bromide cleavage yields dipeptide containing PHE and PRO and a hexapeptide containing all the others C. Chymotrypsin cleaves the hormone into two tetrapeptides of composition ( ASP, ARG, TYR, VAL) and (ILE, MET, PHE, PRO) D. The dipeptide of composition (PRO, PHE) cannot be cleaved by either chymotrypsin or carboxypeptidase ( cleaves any C- terminal amino acid) What is the sequence of this protein?
