dc.description.abstract | Bio-catalysis by enzymes on solid surfaces has been implemented in several practical applications. However, the current methods for efficient enzyme immobilization with retained activity need further development. Herein, simple, rapid, and economical, bio-affinity-based approach was developed for the direct immobilization with high activity recovery of the Bacillus subtilis catalase (CAT), recombinantly expressed in Escherichia coli. Silaffin-3-derived pentalysine cluster (Sil3K) from Thalassiosira pseudonana and its mutant variant (penta-arginine peptide; Sil3R) were used for the first time in the non-covalent immobilization of the recombinant enzyme on silica particles. The fusion proteins CAT-Sil3K and CAT-Sil3R were selectively loaded from the cell lysates onto the silica surface. Unexpectedly, the Lys-based tag (Sil3K) was the superior to Arg-based tag (Sil3R) or tag-less system for the high recovery of CAT activity upon immobilization; an 8.4-fold and 1.5-fold increase in the catalytic activity was observed for CAT-Sil3K compared with the tag-less CAT and CAT-Sil3R, respectively. Furthermore, the CAT-Sil3K immobilized on silica particles exhibited improved thermal, pH and storage stabilities, and retained 72% of the initial activity after five reaction cycles. Moreover, CAT-Sil3K was released with approximately 85% recovery and 91% purity, in a biologically active form when free lysine solution was used as the eluent. Our data proved that Sil3K-tag, 12-mer peptide, can be a highly promising silica-affinity tag for effective enzyme immobilization with preserved activity. Additionally, the novel findings obtained here may open new route not only for cost-effective enzyme immobilization approaches but also for high recovery of enzyme activity. (C) 2020 Elsevier B.V.
