CRYSTAL STRUCTURE OF PHYTASE WITH MAGNESIUM FROM BACILLUS AMYLOLIQUEFACIENS
OverviewOverview
Phytases hydrolyze phytic acid to less phosphorylated myo-inositol, derivatives and inorganic phosphate. A thermostable phytase is of great, value in applications for improving phosphate and metal ion availability, in animal feed, and thereby reducing phosphate pollution to the, environment. Here, we report a new folding architecture of a six-bladed, propeller for phosphatase activity revealed by the 2.1 A crystal, structures of a novel, thermostable phytase determined in both the, partially and fully Ca2+-loaded states. Binding of two calcium ions to, high-affinity calcium binding sites results in a dramatic increase in, thermostability (by as much as approximately 30 degrees C in melting, temperature) by joining loop segments remote in the amino acid sequence., Binding of three ...
