Comments

Comment Type Description
Catalytic Activity 1D-myo-inositol 1,4-bisphosphate + H(2)O = 1D- myo-inositol 4-phosphate + phosphate.
Catalytic Activity Adenosine 3',5'-bisphosphate + H(2)O = adenosine 5'-phosphate + phosphate.
Cofactor Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
Enzyme Regulation Inhibited by Li(+) (IC(50)=10 millimolar), Na(+) (IC(50)=200 millimolar) and Ca(2+) (IC(50)=0.03 millimolar).
Function Converts adenosine 3'-phosphate 5'-phosphosulfate (PAPS) to adenosine 5'-phosphosulfate (APS) and 3'(2')-phosphoadenosine 5'- phosphate (PAP) to AMP. May regulate the flux of sulfur in the sulfur-activation pathway by converting PAPS to APS (By similarity). Prevents both the toxicity of PAP on RNA processing enzymes as well as the product inhibition by PAP of sulfate conjugation. Is also able to hydrolyze inositol 1,4-bisphosphate. {ECO:0000250, ECO:0000269|PubMed:10205895}.
Miscellaneous Substrate preference is 3'-phosphoadenosine 5'- phosphate (PAP) > adenosine 3'-phosphate 5'-phosphosulfate (PAPS)>> inositol 1,4-bisphosphate. No activity observed against 3' or 5'-AMP, inositol monophosphate and fructose-1,6- bisphosphate.
Pathway Signal transduction; phosphatidylinositol signaling pathway.
Similarity Belongs to the inositol monophosphatase family. {ECO:0000305}.
Tissue Specificity Very low expression in roots, leaves, stems, flowers and siliques.
