MODIFIED PHYTASES

摘要

The present invention describes modified phytases. These phytases are modified as compared to a model phytase in various positions, in particular to increase the thermostability of the modified phytase as compared to that of the model phytase. The modified phytases have further retained favourable properties of Aspergillus niger phytase, in particular because specific amino acid residues of Aspergillus niger phytase are retained in the modified phytase.
