Protein

SAL1 phosphatase

Gene

SAL1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-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. May regulate the flux of sulfur in the sulfur-activation pathway by converting PAPS to APS. May play a role in the biosynthesis of sulfate conjugates and RNA processing. Is also able to hydrolyze inositol 1,4-bisphosphate and inositol 1,3,4-trisphosphate. Could be considered as a negative regulator of abscisic acid (ABA)- and stress-responsive genes, through modulating the inositol 1,4,5-trisphosphate (IP3) turnover. Is also involved in salt tolerance. Acts as a suppressor of virus- and transgene-induced silencing.3 Publications

Catalytic activityi

Adenosine 3',5'-bisphosphate + H2O = adenosine 5'-phosphate + phosphate.
1D-myo-inositol 1,4-bisphosphate + H2O = 1D-myo-inositol 4-phosphate + phosphate.

Cofactori

Enzyme regulationi

Inhibited by Li+ (IC50=0.20 millimolar) and Na+ (IC50=200 millimolar).

Miscellaneous

Mutation in the FRY1 gene results in super-induction of abscisic acid (ABA)- and stress-responsive genes, due to inositol 1,4,5-trisphosphate (IP3) accumulation.
Substrate preference is 3'-phosphoadenosine 5'-phosphate (PAP) = adenosine 3'-phosphate 5'-phosphosulfate (PAPS)> inositol 1,4-bisphosphate >> inositol 1,4,5-trisphosphate. No activity observed against 3' or 5'-AMP, inositol monophosphate and fructose-1,6-bisphosphate.
