    • A new method to obtain pure zymogen-derived peptidases is presented. The key strategy is to install a polyhistidine peptide tag on the N-terminus of the propeptide sequence of a zymogen. After expression, purification, and folding of the protein, autocatalytic posttranslational cleavage and filtration through a nickel affinity column gives pure, functional peptidase. This method takes advantage of the nickel affinity chromatography system that removes both zymogen peptide and nonfunctional… CONTINUE READING
