Abstract
Disclosed is a thermostable phytase, in which at least one pair of introduced disulfide bonds is included in the amino acid sequence of wild-typephytase or mutantphytase, and after the introduction, the properties of the phytase can be improved, especially the heat stability, steam stability and granulation stability, which are superior to those of the existing wild-type or mutant phytase; compared to the engineered phytase in which disulfide bonds are introduced, the heat stability is also significantly improved.
