摘要

Nocardiopsis sp.的角化酶TOA-1 （NAPase）在工业和医学应用中具有重要的潜力。本研究在枯草芽孢杆菌中建立了NAPase的异源分泌表达系统。重组酶表现出与天然酶相当的催化性能，表明其适合进一步的蛋白质工程。本研究为提高NAPase活性和稳定性，加快其生物技术应用奠定了基础。

Secretory expression in Bacillus subtilis, purification and characterization of a persistent protein-degrading enzyme from Nocardiopsis sp. TOA-1.

Keratinase from Nocardiopsis sp. TOA-1 (NAPase) holds significant potential for industrial and medical applications. Here, we developed a heterologous secretory expression system for NAPase in Bacillus subtilis. The recombinant enzyme exhibited catalytic properties comparable to the native enzyme, demonstrating its suitability for further protein engineering. This work provides a foundation for enhancing NAPase activity and stability, expediting its biotechnological applications.
