The enzyme 5-phytase [1] (EC 3.1.3.72) catalyzes the reaction
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 5-phosphohydrolase.
Of the hundreds of phytase enzymes that have been characterized in the literature, only two have been characterized as 5-phytases. [2][ needs update] A histidine acid phosphatases purified from lily pollen [1] and a protein tyrosine phosphatase-like phytase from Selenomonas ruminantium subsp. lactilytica [2] were both found to have specificity for the 5-phosphate position of myo-inositol hexakisphosphate.
As of late 2007, only the phytase purified from lily pollen had its structure solved, with PDB accession codes 1U24, 1U25, 1U26, 2B4O, 2B4P, and 2B4U.
