- Electrophoresis Macmillan Learning Chymotrypsin is a protease with a molecular mass of 25.6 kDa. The figure shows a stained SDS polyacrylamide gel with a single band in lane I and three bands of lower molecular weight in lane 2. Lane I contains a preparation of chymotrypsin and lane 2 contains chymotrypsin pre-treated with performic acid. 1 2 Why does performic acid treatment of chymotrypsin generate three bands in lane 2? ° Chymotrypsin self-digests on the carboxyl-terminal side of phenylalanine, tryptophan, or tyrosine residues. The three peptides are impurities in the original chymotrypsin sample. Performic acid cleaves proteins on the carboxyl-terminal side of lysine and arginine residues. Performic acid cleaves the disulfide bonds holding together the three subunits of chymotrypsin. Correct Answerarrow_forwardExtracts from the bacterium Bacillus brevis contain a peptide with antibiotic properties. This peptide forms complexes with metal ions and seems to disrupt ion transport across the cell membranes of other bacterial species, leading to bacterial death. The structure of the peptide has been determined from a series of observations. (a) Complete acid hydrolysis of the peptide, followed by amino acid analysis, yielded equimolar amounts of Leu, Orn, Phe, Pro, and Val. Orn is ornithine, an amino acid not present in proteins but present in some peptides. Orn has the structure H 'H,N-CH, - CH2 CH2 CH2 - C - COO- NH, (b) The molecular weight of the peptide is approximately 1,200 Da. (c) The peptide failed to undergo hydrolysis when treated with the enzyme carboxypeptidase.
