Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (PHYT_BACSD | O66037)
molecular function
    GO:0016158    3-phytase activity    Catalysis of the reaction: myo-inositol hexakisphosphate + H2O = D-myo-inositol 1,2,4,5,6-pentakisphosphate + phosphate.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
biological process
    GO:0016311    dephosphorylation    The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
