General annotation (Comments)

Function

Catalyzes the hydrolysis of inorganic orthophosphate from phytate. Only phytate, ADP, and ATP were hydrolyzed (100, 75, and 50% of the relative activity, respectively).

Catalytic activity

Myo-inositol hexakisphosphate + H2O = 1D-myo-inositol 1,2,4,5,6-pentakisphosphate + phosphate.

Cofactor

Calcium. Required for its activity and/or stability.

Subcellular location

Secreted.

Induction

By phytate.

Sequence similarities

Contains 1 BPP (beta-propeller phytase) domain.

Biophysicochemical properties

pH dependence:

Optimum pH is 7.

Temperature dependence:

Optimum temperature is 55 degrees Celsius.
