Protein
3-phytase A
Gene
phyA
Organism
Aspergillus terreus
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the hydrolysis of inorganic orthophosphate from phytate. Releases 5 of the 6 phosphate groups to yield the end product myo-inositol 2-monophosphate. Specific for phytate.1 Publication

Catalytic activityi

Myo-inositol hexakisphosphate + H2O = 1D-myo-inositol 1,2,4,5,6-pentakisphosphate + phosphate.

Kineticsi

  1. KM=10.6 µM for phytate1 Publication

pH dependencei

Optimum pH is 5.5. Active from 2.5 to 7.5 with phytic acid as substrate. The optimum pH is shifted to more acidic values with 4-nitrophenyl phosphate as substrate.
