Protein

Purple acid phosphatase 15

Gene

PAP15

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acid phosphatase activity with p-nitrophenyl phosphate (pNPP), D-myoinositol 1-phosphate (Ins1P1), phytic acid and Myo-inositol hexakisphosphate. Low or no activity with Glc-6-P and ATP. Confers shoot growth stimulation, enhanced salt and osmotic stress tolerance, and ABA insensitivity. May modulate ascorbic acid (AsA) levels by controlling the input of myoinositol into this branch of AsA biosynthesis.1 Publication

Catalytic activityi

Myo-inositol hexakisphosphate + H2O = myo-inositol pentakisphosphate + phosphate.
A phosphate monoester + H2O = an alcohol + phosphate.

Cofactori

Protein has several cofactor binding sites:
  • Fe cationBy similarityNote: Binds 1 Fe cation per subunit.By similarity
  • Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity

pH dependencei

Optimum pH is 4.5.1 Publication
