General annotation (Comments)

Catalytic activity

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; disulfide-linked By similarity.

Subcellular location

Isoform 1: Secreted By similarity Ref.1.

Isoform 2: Cytoplasm Probable Ref.1.

Tissue specificity

Expressed in roots, stems, leaves, flowers and siliques. Ref.5

Induction

By phosphate deprivation, mostly isoform 2. Ref.1

Sequence similarities

Belongs to the metallophosphoesterase superfamily. Purple acid phosphatase family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9SIV9-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q9SIV9-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-128: MGRVRKSDFG...IHHCPIRNLE → MLWFFLLQ
Note: May be due to intron retention. No experimental confirmation available.
