Determine the sequence of a tetra peptide: 1)The second amino acid has a phenol in the side chain. 2)The amino acid at the amino terminal is acidic and the only acidic amino acid present. 3)Amino acid with CH3 side chain at C terminal. 2)Pepsin - cuts on the C-terminal side of phenylalanine, leucine, and glutamic acid. When digested with the pepsin the peptide gives a negative amino acid residue and neutral tripeptide 3)Cyanogen bromide- cuts on the C-terminal side of...

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...
