The present invention relates to phytase variants, their preparation and uses, which phytase variants, when aligned according to FIG., are amended as compared to a model phytase in at least one of a number of positions. Preferred model phytases are basidiomycete and ascomycete phytases, such asphytase andphytases. Preferred phytase variants exhibits amended activity characteristics, such as improved specific activity and/or improved thermostability.

Phytase variants

A process for the production of a modified phytase with a desired property improved over the property of the corresponding unmodified phytase is disclosed, as well as modified phytases, polynucleotides encoding modified phytases, and animal feed including modified phytases.

Modified phytases

The present invention relates to phytase variants, their preparation and uses, which phytase variants, when aligned according to FIG. are amended as compared to a model phytase in at least one of a number of positions. Preferred model phytases are basidiomycete and ascomycete phytases, such as Peniophora phytase and Aspergillus phytases. Preferred phytase variants exhibits amended activity characteristics, such as improved specific activity and/or improved thermostability.
