Protein

3'(2'),5'-bisphosphate nucleotidase 1

Gene

Bpnt1

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Converts adenosine 3'-phosphate 5'-phosphosulfate (PAPS) to adenosine 5'-phosphosulfate (APS) and 3'(2')-phosphoadenosine 5'- phosphate (PAP) to AMP. Has 1000-fold lower activity towards inositol 1,4-bisphosphate (Ins(1,4)P2) and inositol 1,3,4-trisphosphate (Ins(1,3,4)P3), but does not hydrolyze Ins1P, Ins(3,4)P2, Ins(1,3,4,5)P4 or InsP6.1 Publication

Catalytic activityi

Adenosine 3',5'-bisphosphate + H2O = adenosine 5'-phosphate + phosphate.

Cofactori

Enzyme regulationi

Uncompetitive inhibition by micromolar concentrations of lithium. Competitive inhibition by inositol 1,4-bisphosphate. Inhibited by calcium ions.1 Publication
