inositol monophosphatase family protein similar to human inositol polyphosphate 1-phosphatase (INPP1) which hydrolyzes the 1 position phosphate from inositol 1,4-bisphosphate (Ins(1,4)P2) or inositol 1,3,4-trisphosphate (Ins(1,3,4)P3), and to human 3'(2'),5'-bisphosphate nucleotidase 1 (BPNT1) which converts adenosine 3'-phosphate 5'-phosphosulfate (PAPS) to adenosine 5'-phosphosulfate (APS) and 3'(2')-phosphoadenosine 5'- phosphate (PAP) to AMP and has 1000-fold lower activity towards (Ins(1,4)P2) and (Ins(1,3,4)P3)

IPPase; Inositol polyphosphate-1-phosphatase, a member of the Mg++ dependent family of inositol monophosphatase-like domains, hydrolyzes the 1' position phosphate from inositol 1,3,4-trisphosphate and inositol 1,4-bisphosphate. Members in this group may also exhibit 3'-phosphoadenosine 5'-phosphate phosphatase activity, and they all appear to be inhibited by lithium. IPPase is one of the proposed targets of Li+ therapy in manic-depressive illness.

3'(2'),5'-bisphosphate nucleotidase, bacterial; Sulfate is incorporated into 3-phosphoadenylylsulfate, PAPS, for utilization in pathways such as methionine biosynthesis. Transfer of sulfate from PAPS to an acceptor leaves adenosine 3'-5'-bisphosphate, APS. This model describes a form found in bacteria of the enzyme 3'(2'),5'-bisphosphate nucleotidase, which removes the 3'-phosphate from APS to regenerate AMP and help drive the cycle.

CysQ, a 3'-Phosphoadenosine-5'-phosphosulfate (PAPS) 3'-phosphatase, is a bacterial member of the inositol monophosphatase family. It has been proposed that CysQ helps control intracellular levels of PAPS, which is an intermediate in cysteine biosynthesis (a principal route of sulfur assimilation).

Inositol-monophosphatase-like domains. This family of phosphatases is dependent on bivalent metal ions such as Mg++, and many members are inhibited by Li+ (which is thought to displace a bivalent ion in the active site). Substrates include fructose-1,6-bisphosphate, inositol poly- and monophosphates, PAP and PAPS, sedoheptulose-1,7-bisphosphate and probably others.

IMPase, inositol monophosphatase and related domains. A family of Mg++ dependent phosphatases, inhibited by lithium, many of which may act on inositol monophosphate substrate. They dephosphorylate inositol phosphate to generate inositol, which may be recycled into inositol lipids; in eukaryotes IMPase plays a vital role in intracellular signaling. IMPase is one of the proposed targets of Li+ therapy in manic-depressive illness. This family contains some bacterial members of the inositol monophosphatase family classified as SuhB-like. E. coli SuhB has been suggested to participate in posstranscriptional control of gene expression, and its inositol monophosphatase activity doesn't appear to be sufficient for its cellular function. It has been proposed, that SuhB plays a role in the biosynthesis of phosphatidylinositol in mycobacteria.

PAP-phosphatase_like domains. PAP-phosphatase is a member of the inositol monophosphatase family, and catalyses the hydrolysis of 3'-phosphoadenosine-5'-phosphate (PAP) to AMP. In Saccharomyces cerevisiae, HAL2 (MET22) is involved in methionine biosynthesis and provides increased salt tolerance when over-expressed. Bacterial members of this domain family may differ in their substrate specificity and dephosphorylate different targets, as the substrate binding site does not appear to be conserved in that sub-set.

Fructose-1,6-bisphospatase (both the major and the glpX-encoded variant) hydrolyze fructose-1,6,-bisphosphate to fructose-6-phosphate in gluconeogenesis. Inositol-monophosphatases and inositol polyphosphatases play vital roles in eukaryotic signalling, as they participate in metabolizing the messenger molecule Inositol-1,4,5-triphosphate. Many of these enzymes are inhibited by Li+.
