Heterologous expression and characterization of B. velezensis SW5 serine protease involved in the hydrolysis of anchovy protein.

The novel SPr-SW5 was successfully expressed in B. subtilis WB800N. It exhibited excellent temperature stability, and good tolerance to several metal ions. In addition, the anchovy hydrolyzed by expressed SPr-SW5 has good antioxidant ability. Overall, this research lays a good foundation for SPr-SW5 in exploration and application of food industry as enzyme preparation. This article is protected by copyright. All rights reserved.
