General description
Phytase catalyzes the hydrolysis of phytic acid to inositol and free orthophosphate.
Application
Phytase has been used in a study to quantify the number of feedstuffs showing significant phytase activity. It has also been used in a study to investigate the effect of adjusting the pH to 5.0 (optimum for wheat phytase) during whole wheat bread making on phytase activity.
Biochem/physiol Actions
Wheat phytase can degrade inositol phosphate-6 and 5 at a pH of 4 and 5.
Analysis Note
Crude
Other Notes
One unit will liberate 1.0 μmole of inorganic phosphorus from 1.5 mM phytate per min at pH 5.15 at 55 °C.
