Application

Acid phosphatase from potato has been used in a study to assess the potential allergenicity of novel gene products. [1] It has also been used in a study to remove eight phosphate groups from casein at a pH of 7.0. [2]

The activity of potato acid phosphatase in various surfactant medias was examined. Bis(2- ethylhexyl)sodium sulfosuccinate, Brij 35, and SDS at 3mM inhibited phosphatase activity while the surfactant cetyltrimethylammonium bromide enhanced activity. [3]

Biochem/physiol Actions

Acid phosphatases (APase) are a family of enzymes that non-specifically catalyze the hydrolysis of monoesters and anhydrides of phosphoric acid to produce inorganic phosphate at an optimum pH of 4 to 7.

General description

Acid phosphatase from potato is a phosphomonoesterase, which can appear in multiple molecular forms of similar molecular mass but with different isoelectric points. [4]

Other Notes

One unit will hydrolyze 1.0 μmole of p-nitrophenyl phosphate per min at pH 4.8 at 37 °C.

Stability and activity of potato acid phosphatase in aqueous surfactant media.

J Lalitha et al.

Biochemistry and molecular biology international, 41(4), 797-803 (1997-04-01)

The effect of three different classes of surfactants viz., anionic, cationic and neutral on catalytic activity of potato acid phosphatase (AcPase) was studied. Anionic surfactants bis(2-ethylhexyl) sodium sulfosuccinate (AOT) and sodium dodecyl sulfate (SDS) inhibited AcPase activity completely at 3

Isolation and characterization of a homogeneous isoenzyme of wheat germ acid phosphatase.

P P Waymack et al.

Archives of biochemistry and biophysics, 288(2), 621-633 (1991-08-01)

An acid phosphatase (orthophosphoric monoester phosphohydrolase, acid optimum; EC 3.1.3.2) isoenzyme from wheat germ was purified 7000-fold to homogeneity. The effect of wheat germ sources and their relationship to the isoenzyme content and purification behavior of acid phosphatases was investigated.
