摘要： The invention relates to a phytase derived from Citrobacter braakii and related phytases. The phytases belong to the acid histidine phosphatase family, are acid-stable, of an excellent performance in animal feed, of a high specificity towards the substrate phytate, and expectedly of a high specific activity. The invention also relates to the corresponding DNA, the recombinant and wild-type production of the phytases, as well as the use thereof.

摘要： The present invention relates to isolated polypeptides having phytase activity, recombinant DNA sequences encoding such polypeptides, methods of producing such polypeptides, and the use of the polypeptides in transgenic plants. The invention discloses polypeptides having affinity for the substrate phytate (1, 2, 3, 4, 5, 6 myo-inositol-hexakisphosphate, phytic acid), comprising an amino acid sequence as described by the invention. Furthermore, the invention discloses DNA fragments encoding the polypeptides, and cDNA fragments encoding the polypeptides. The polypeptides of the invention may, for example, be used as an additive in animal feeds, an additive in food for human consumption, or to extract proteins from rice bran. The invention also concerns a transgenic plant or part thereof, wherein the plant or part thereof has been genetically modified to comprise a polypeptide as defined by the invention.
摘要翻译：本发明涉及具有植酸酶活性的分离多肽，编码此类多肽的重组DNA序列，生产此类多肽的方法以及该多肽在转基因植物中的用途。本发明公开了包含本发明描述的氨基酸序列的对底物植酸盐（1,2,3,4,5,6肌醇六磷酸，植酸）具有亲和力的多肽。此外，本发明公开了编码该多肽的DNA片段和编码该多肽的cDNA片段。本发明的多肽可以例如用作动物饲料中的添加剂，用于人类食用的食品中的添加剂，或从米糠提取蛋白质。本发明还涉及转基因植物或其部分，其中植物或其部分已被遗传修饰以包含本发明所定义的多肽。
