A novel bacterial phytase from a Bacillus amyloliquefaciens strain was crystallized using the hanging-drop vapour-diffusion method. The amino-acid sequence of the enzyme does not show any homology to those of other known phytases or phosphatases, with the exception of a phytase from Bacillus subtilis. The enzyme exhibits a thermal stability which is strongly dependent on calcium ions. High-quality single crystals of the enzyme in the absence of calcium ions were obtained using a precipitant… CONTINUE READING
