Deduce the sequence of a heptapeptide that contains the amino
acids Met, Gln, Phe, Leu, Cys, Val, and Arg, from the following
experimental data. Edman degradation cleaves Cys from the
heptapeptide, and carboxypeptidase forms Gln and a hexapeptide.
Treatment of the heptapeptide with chymotrypsin forms a hexapeptide
and a single amino acid. Treatment of the heptapeptide with trypsin
forms a pentapeptide and a dipeptide. Partial hydrolysis forms Gln,
Cys, Phe, and the tripeptides Leu-Met-Val and Met-Val-Arg.

1. Partial hydrolysis of lysozyme yielded an octapeptide that was later identified as the N-terminal segment of the protein. From the following information, determine the sequence of this octapeptide. a. The following amino acids were identified after complete hydrolysis of the octapeptide: Arginine (Arg) Glycine (Gly) Phenylalanine (Phe) Cysteine (Cys) Leucine (Leu) Valine (Val) Glutamic Acid (Glu) Lysine (Lys) b. Treatment of the octapeptide with dinitroflurobenzene (Sanger reagent) followed by complete hydrolysis gave lysine (Lys) labeled with two dinitrophenyl (DNP) groups. c. Treatment of the octapeptide with trypsin gave lysine...

2. A mutant form of polypeptide hormone angiotensin II has the amino acid composition: Ile, Arg, Met, Leu, Phe, Asp, Tyr, and Val. The following observations are made: 1) Treatment with trypsin yields a dipeptide containing Asp and Arg, and a hexapeptide with all the rest. 2) Cyanogen bromide yields a dipeptide containing Phe and Leu and a hexapeptide containing all the rest. 3) Chymotrypsin cleaves the hormone into two tetrapeptides of composition: Val, Tyr,...
