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
