General annotation (Comments)

Function

Acid phosphatase activity with p-nitrophenyl phosphate (pNPP), D-myoinositol-1-phosphate (Ins1P1), phytic acid and Myo-inositol hexakisphosphate. Low or no activity with Glc-6-P and ATP. Confers shoot growth stimulation, enhanced salt and osmotic stress tolerance, and ABA insensitivity. May modulate ascorbic acid (AsA) levels by controlling the input of myoinositol into this branch of AsA biosynthesis. Ref.4

Catalytic activity

Myo-inositol hexakisphosphate + H2O = myo-inositol pentakisphosphate + phosphate.

A phosphate monoester + H2O = an alcohol + phosphate.

Cofactor

Binds 1 iron ion per subunit By similarity.

Binds 1 zinc ion per subunit By similarity.

Subunit structure

Homodimer By similarity.

Subcellular location

Secreted By similarity.

Tissue specificity

Expressed in roots, stems, cotyledons, leaves, flowers and siliques. Ref.4 Ref.1

Sequence similarities

Belongs to the metallophosphoesterase superfamily. Purple acid phosphatase family.

Biophysicochemical properties

pH dependence:

Optimum pH is 4.5.
