Abstract
The present invention relates to an isolated polypeptide exhibiting phytase activity, the corresponding cloned DNA sequences, a process for preparing the polypeptide, and the use thereof for a number of industrial applications, in particular in animal feed. The novel phytase is derived from Peniophora lycii and has some interesting features, such as high initial affinity for the 6-position of phytic acid, a high intial rate of liberating phosphate from phytic acid and an exceptionally high specific activity.
