Expression and immobilization of trypsin-like domain of serine protease from Pseudomonas aeruginosa for improved stability and catalytic activity.

Protein engineering and enzyme immobilization strategies have produced numerous biocatalysts for modern industrial applications. In this study, we have also used these two strategies for improving the operational stability and catalytic efficiency of serine protease from Pseudomonas aeruginosa. The enzyme serine protease was truncated to separate its trypsin-like domain from the PDZ1 and PDZ2 domains.
