Protein
Bifunctional purple acid phosphatase 26
Gene
PAP26, At5g34850, T5E15.10
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Metallo-phosphoesterase involved in phosphate metabolism. Acid phosphatase activity with phosphoenolpyruvate, inorganic pyrophosphate, phenyl-phosphate and p-nitrophenyl-phosphate as the most effective substrates. No activity with phytic acid, phosphocholine or bis-p-nitrophenyl-phosphate. Has a peroxidase activity at alkaline pH.1 Publication

Catalytic activityi

A phosphate monoester + H2O = an alcohol + phosphate.
2 phenolic donor + H2O2 = 2 phenoxyl radical of the donor + 2 H2O.

Cofactori

Binds 1 iron ion per subunit By similarity.
Binds 1 zinc ion per subunit By similarity.

Enzyme regulationi

Activated by Mg2+, Co2+, Mn2+ and Ba2+. Inhibited by Fe2+, Cu2+, Zn2+, NaF, molybdate, arsenate, vanadate and inorganic phosphate. No effect of tartrate, Asp, Gln, glutathione, Asn, ascorbic acid and phosphite.

Absorptioni

Abs(max)=520 nm1 Publication

Kineticsi

  1. KM=0.8 mM for phosphoenolpyruvate (for the phosphatase activity)

pH dependencei

Optimum pH is 5.6 for the phosphatase activity and 8.8 for the peroxidase activity.
