(A) Schematic illustration of the bioreductive release of MEL from pacMELClv and degradation of the MEL component by α-chymotrypsin (Protein Data Bank ID 2CHA). (B) Agarose gel electrophoresis (2%) of pacMELClv treated with 10 mM DTT with varying treatment times. (C) The release profile for pacMELClv was determined by gel band densitometry analysis. (D) Polyacrylamide gel electrophoresis showing α-chymotrypsin degradation of pacMELClv, YPEG-MEL, and free MEL. The percentage of MEL degradation after 120 min of treatment is shown in (E). **P < 0.01, and ****P < 0.0001 (two-tailed t-test).
