Hazard Information

Chemical Properties

This white lyophilized powder is soluble in water with an optimal pH of less than 7.0. It contains three isoenzymes: E_I, E_II, and E_III, with optimal pH values of 5.5, 4.5, and 4.0, respectively. It exhibits peak activity against pyrophosphate. Stability: The enzyme solution maintains activity for 5 months when stored in toluene at 10°C. Inhibitors include orthophosphate, molybdate, and fluoride. It promotes the release of inorganic phosphate from phosphate esters in the blood. The enzyme reaction is: orthophosphate monoester + H2O═alcohol + orthophosphate.

Uses

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

Uses

Sweet potato acid phosphatase has been used in a study as a pre-column enzyme reactor via a covalent bond with glutaraldehyde and aminopropyl controlled-pore glass. It has also been used in a study to investigate the use of tyrosine, histidine, and cysteine as ligands for Mn(III) in sweet potato phosphatase.

Definition

Wheat germ acid phosphatase (WGAP; Phosphatase, Acid from wheat germ) is a commercial preparation of partially purified protein commonly used in laboratory settings for non-specific enzymatic dephosphorylation.

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 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.
