Taxonomic identifier

330879 [NCBI]

Taxonomic lineage

cellular organisms › Eukaryota › Opisthokonta › Fungi › Dikarya › Ascomycota › saccharomyceta › Pezizomycotina › leotiomyceta › Eurotiomycetes › Eurotiomycetidae › Eurotiales › Trichocomaceae › mitosporic Trichocomaceae › Aspergillus › Neosartorya fumigata

Protein attributes

Sequence length	465 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Catalyzes the hydrolysis of inorganic orthophosphate from phytate.
Catalytic activity	Myo-inositol hexakisphosphate + H2O = 1D-myo-inositol 1,2,4,5,6-pentakisphosphate + phosphate.
Subcellular location	Secreted.
Sequence similarities	Belongs to the histidine acid phosphatase family.
Biophysicochemical properties	pH dependence: Highly active from pH 3 to 5 with 4-nitrophenyl phosphate as substrate, and from 2.5 to 7.5 with phytic acid. Temperature dependence: Able to withstand temperatures up to 100 degrees Celsius over a period of 20 min, with a loss of only 10% of the initial enzymatic activity.
Sequence caution	The sequence EAL89926.2 differs from that shown. Reason: Erroneous initiation.
