5-phytase

5-phytase

In enzymology, a 5-phytase (EC number|3.1.3.72) is an enzyme that catalyzes the chemical reaction

:myo-inositol hexakisphosphate + H2O ightleftharpoons 1L-myo-inositol 1,2,3,4,6-pentakisphosphate + phosphate

Thus, the two substrates of this enzyme are myo-inositol hexakisphosphate and H2O, whereas its two products are 1L-myo-inositol 1,2,3,4,6-pentakisphosphate and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is myo-inositol-hexakisphosphate 5-phosphohydrolase.

tructural studies
