A purified and modified phytase enzyme from Escherichia coli K12 appA phytase is provided. The enzyme has phytase activity and improved thermal tolerance as compared with the wild-type enzyme. In addition, the enzyme has improved protease stability at low pH. Glycosylation of the modified phytase provided a further improved enzyme having improved thermal tolerance and protease stability. The enzyme can be produced from native or recombinant host cells and can be used to aid in the digestion of phytase where desired. In particular, the phytase of the present invention can be used in foodstuffs to improve the feeding value of phytase rich ingredients.

L'invention porte sur une enzyme, de type phytase, purifiée et modifiée dérivant de la phytase de l'Escherichia coli K12 appA. Cette enzyme, qui présente l'activité de la phytase et une tolérance accrue à la chaleur par rapport à l'enzyme native, a en outre une stabilité de protéase améliorée sous faible pH. Par glycosylation de la phytase modifiée, on obtient une amélioration supplémentaire en matière de tolérance à la chaleur et de stabilité de protéase. L'enzyme, qui peut être obtenue à partir de cellules hôtes natives ou de recombinaison, peut lorsque c'est souhaitable servir à améliorer la digestion. Elle peut en particulier être intégrée à des produits alimentaires riches en phytase pour en augmenter le pouvoir nutritif.
