General Stability

General Stability Organism
denaturation in urea, in presence of 2 mM dithiothreitol, the inactivation and unfolding are greatly enhanced at the same concentration of denaturant, the enzyme may be a 3-phytase, EC 3.1.3.8, or a 6-phytase, EC 3.1.3.26. The product of the hydrolysis of myo-inositol hexakisphosphate i.e. myo-inositol 1,2,3,4,5-pentakisphosphate or myo-inositol 1,3,4,5,6-pentakisphosphate has not been identified Aspergillus niger

The enzyme may be a 3-phytase (EC 3.1.3.8), or a 4-phytase (synonym 6-phytase, EC 3.1.3.26). The product of the hydrolysis of myo-inositol hexakisphosphate to 1D-myo-inositol 1,2,4,5,6-pentakisphosphate or alternatively 1D-myo-inositol 1,2,3,5,6-pentakisphosphate has not been identified.
