Opis ogólny

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

Zastosowanie

Potato acid phosphatase is used as a dephosphorylating reagent in thiochrome assays for the detection of thiamin in biological samples. In this assay, it was shown to be more effective than acid phosphatases from wheat germ or α-amylase.
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.

Działania biochem./fizjol.

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 by the following reaction: APaseR-PO4 + H2O --------------- R-OH + HOPO3 2+Their function in the production, transport, and recycling of phosphate is critical for the metabolic and energy transduction processes of the cell. As a group, Apases may be as important as kinases in regulatory processes.

Definicja jednostki

Induction of phosphatase activity is an important component of the plant cell response to phosphate deficiency. Suspension cell cultures of Brassica nigra contain two major inducible acid phosphatase (APase) isozymes; vacuolar phosphoenolpyruvate (PEP) APase and cell wall nonspecific APase. Polyclonal

Enzymatic Assay of Acid Phosphatase (EC 3.1.3.2)

Enzymatic Assay of Acid Phosphatase (EC 3.1.3.2)

Test enzymatyczny kwaśnej fosfatazy (EC 3.1.3.2)

Aby zmierzyć aktywność fosfatazy kwaśnej, procedura ta wykorzystuje fosforan p-nitrofenylu w teście kolorymetrycznym. Aktywność enzymatyczna jest mierzona przy 410 nm przy użyciu spektrofotometru.
