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...
