The Discovery, Molecular Cloning, and Characterization of Dextransucrase DexA and Its Active Truncated Mutant from NN710.

Dextransucrases play a crucial role in the production of dextran from economical sucrose; therefore, there is a pressing demand to explore novel dextransucrases with better performance. This study characterized a dextransucrase enzyme, DexA, which was identified from the NN710. This bacterium was isolated from the soil of growing dragon fruit in Guangxi province, China.

Magnetic CuFeO with intrinsic protease-like activity inhibited cancer cell proliferation and migration through mediating intracellular proteins.

Protease has been widely used in biological and industrial fields. Developing efficient artificial enzyme mimics remains a major technical challenge due to the high stability of peptide bonds. Nanoenzymes with high stability, high activity and low cost, provided new opportunities to break through natural enzyme inherent limitations.
