摘要:
β-螺旋桨植酸酶主要来源于芽孢杆菌,是能够分解植酸释放磷元素,并且与金属离子有关的一类酶。β-螺 旋桨植酸酶具有独有的Ca2+依赖性和对植酸-Ca2+复合物的底物专一性。本文综述以Ca2+为主的金属离子与β-螺旋桨 植酸酶的关系。

Abstract:
β-Propeller phytase (BPPs), mainly derived from Bacillus, is capable of decomposing phytate phosphorus, releasing phosphorus and metal ions associated with a class of enzymes. β-Propeller phytase exhibits a unique Ca2+-dependent catalytic property and high substrate specificity toward phytic acid-Ca2+ complexes. In this paper, the advances achieved in the investigation of the relationship of BPPs and metal ion, especially Ca2+, are summarized in this paper.
Key words: Beta-propeller phytase, Bacillus, thermostability, crystal structure, metal-dependent
