METHOD FOR IMPROVING THERMOSTABILITY OF PHYTASE, MUTANT AND USE

Resumen de: EP4549559A1

The present invention relates to the field of genetic engineering, particularly to method for improving thermo-stability of phytase, mutant and use.The present invention introduces a series of mutations to the phytase APPAmut4, which may involve introducing disulfide bonds, reducing the free energy of unfolding, optimizing the key residues in the coevolution process, and significantly improving the thermal stability of the phytase. Among the mutants of the present invention, the optimal mutant APPAmut9 retains about 70% of its activity after being treated for 5 minutes at 100 °C, while the phytase APPAmut4 has already been inactivated. Therefore, the present invention overcomes the shortcomings of the prior art and provides phytase mutants with high thermal stability suitable for wide application in fields such as energy, food, and feed.
