myo-inositol hexakisphosphate + H2O = 1D-myo-inositol 1,2,3,5,6-pentakisphosphate + phosphate
The product can also be designated as 1L-myo-inositol 1,2,3,4,5-pentakisphosphate when the 1L numbering is applied. Therfore the enzyme is frequently called 6-phytase.

Ca2+ turns out to be also required for the substrate because the enzyme is only able to hydrolyze the calcium-phytate complex. 4 mol of Ca2+ bind to 1 mol of phytate
Ca2+
-
enhances thermal stablity and shows an impact on pH-optimum and temperature optimum
Ca2+
is found essential for both refolding and activity of the enzyme
Ca2+
-
the crystal structure of the enzyme in complex with inorganic phosphate reveals that two phosphates and four calcium ions are tightly bound at the active site
Ca2+
enzyme is Ca2+-dependent, drastically improves thermal stability of the enzyme

Na+
-
a high concentration of sodium chloride affects the activity of fungal phytase in the pH 3-4 range
Na+
a high concentration of sodium chloride shifts the pH optimum to 2.0 from 5.5
