描述
| 应用 | Acid phosphatase (APase) non-specifically catalyzes the hydrolysis of monoesters and anhydrides of phosphoric acid to produce inorganic phosphate. It is used to study the production, transport, and recycling of phosphate and the metabolic and energy transduction processes of the cell. |
| 产品介绍 | Acid phosphatase is an esterase with broad activity at an optimal pH below 7.0. There are three isozymes, EI, EII, and EIII of similar molecular weight (55 kDa± 5 kDa). Their optimum pH's are 5.5, 4.5, and 4.0 respectively. Acid phosphatase activity was observed by Teller Aladdin Library Archives in 1954 in preparations of a wheat germ lipase described by Singer JBC, 174, 11, in 1948. Equivalent commercial preparations have been distributed labeled as lipase and acid phosphatase thus generating some confusion. Subsequent work has confirmed that the non-specific esterase activity of the wheat germ preparation may be measured both as lipase (triacetin as substrate) and phosphatase. The enzyme assay is based on the work of Brandenberger and Hanson (Helv. Chim. Acta, 36, 900, 1953) and Hofstee ( Arch. Biochem. Biophys., 51, 239, 1954). |
| 备注 | A non-specific esterase partially purified to the 0.35-0.55 fraction by the method described by Singer, JBC, 174, 11 (1948). Also active as a lipase. A lyophilized powder. |
| 生化机理 | 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 4.0–7.0 and the optimal temperature is 45 °C. |
