General description

Orthophosphoric-monoester phosphohydrolase (acid optimum).
Acid phosphatase is a non-specific phosphomonoesterase, found in the cytoplasmic and cell wall sections of swelling potato tubers. It possesses several acidic amino acid residues. It is found to be present in up to six isoforms with varying degree of glycosylation. The major potato isoform is a homodimer having a molar mass of 96kDa.

Biochem/physiol Actions

Acid phosphatase maintains the concentration of inorganic phosphate. It hydrolyzes orthophosphate monoesters under acidic conditions and also takes part in tuber development in potatoes. It eliminates phosphate groups from phosphoproteins, such as casein, riboflavin binding protein, pepsinogen, ovalbumin, and phosvitin.

Storage and Stability

Store at 2 to 8 °C. (Store dry!)

Potato acid phosphatase (EC 3.1.3.2) was used to remove the eight phosphate groups from alphas1-casein. Unlike most acid phosphatases, which are active at pH 6.0 or below, potato acid phosphatase can catalyze the dephosphorylation of alphas1-casein at pH 7.0. Although
