Abstract:
An isolated phytase derived from a microorganism belonging to the genus Monascus, wherein the phytase has the following physiochemical properties:1) Km: 20 &mgr;m when phytic acid is used as a substrate; 2) optimum pH: pH 6.0; 3) pH stability: stable in the range of pH 6.0 to 7.0; 4) optimum temperature: 50Â° C.; 5) temperature stability: stable up to 50Â° C.; 6) substrate specificity: acting on phytic acid, p-nitrophenylphosphate, D-glucose-6-phosphate, fructose-6-phosphate, D-myo-inositol-2-phospate, D-myo-inositol-1-phosphate, D-myo-inositol-1,4-diphosphate, and adenosine triphosphate as the substrate; 7) molecular weight: about 120 kDa (gel filtration method); and 8) isoelectric point: pI 4.8 (chromatofocusing method).
