Acid Phosphatase, MP Biomedicals
Supplier: E. Becker & Co. GmbH
Soluble in distilled H₂O, dilute buffer.
One unit will hydrolyze 1.0 µmole of o-carboxyphenyl phosphate per minute at 25 °C, pH 5.0.
Plant acid phosphatase (APase) is localized in cytosol, vacuoles, and cell walls. Plant acid phosphatase is important for phosphate acquisition to mobilize organic phosphates in the soil. Phosphate starvation induces acid phosphatase generation. Acid phosphatase originates from the aleurone and scutellar tissues during germination. It hydrolyzes phytins, ATP, protein phosphates and nucleotide phosphates. It has a role in general metabolic reactions. Wheat embryo APase consists of four isoenzymes. The molecular mass of wheat germ APase is 58 kDa (gel filtration), the pH Optimum is 5.7, the pH Range is 4.0 to 7.0 and the optimal temperature is 45 °C.
