myo-Inositol hexakisphosphate is also known as phytic acid.

These enzymes belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds.

The systematic name of this enzyme class is myo-inositol-hexakisphosphate 3-phosphohydrolase. Other names in common use include 1-phytase, phytate 1-phosphatase, phytate 3-phosphatase, and phytate 6-phosphatase.[1]

Enzymes of this type participate in inositol phosphate metabolism.

Structural studies

As of late 2007, 12 structures have been solved for this class of enzymes, with PDB accession codes 1CVM, 1IHP, 1POO, 1QFX, 1QLG, 1QWO, 1SK8, 1SK9, 1SKA, 1SKB, 2GFI, and 2POO.
