General annotation (Comments)

Function

Displays a 20-fold higher rate of hydrolysis of the D isoform of inositol 1-phosphate than of the L isoform.

Catalytic activity

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

Cofactor

Magnesium.

Subunit structure

Homotetramer.

Sequence similarities

Belongs to the inositol monophosphatase family.

Sequence caution

The sequence AAD36486.1 differs from that shown. Reason: Frameshift at position 22.
