additional information
-
introduction of about 20 site-directed mutations to obtain a variant with increased sequence selectivity, a predomain that can direct cleavage to the junction of any protein fused to it, and a modified active site to kinetically isolate binding and cleavage reactions. Identification of specific anions that trigger the processing reaction so that column-immobilized mutant enzyme can be used as both the affinity ligand and the processing protease for one-step purification methods
additional information
-
sequential randomization of 12 amino acid positions in calcium-free enzyme. Mutations increase the half-life of enzyme at elevated temperature by 15000fold and partially increase ratio of kcat/KM-value
