WebJan 2, 2024 · The results showed that the optimal temperature for ALP activity was 37 °C, and the optimal pH was 8.5. But ALP was stable at temperatures below 32 °C. The ALP activity remained at 80% when the pH was 8–9.5. The enzyme activity could be activated by Mg 2+, Ca 2+, and inhibited by Cu 2+, Zn 2+, and EDTA.
WebOptimum activity was found to occur at pH 9.13 when the enzyme was incubated with 10 mg. per ml. of glycerophosphate at different pH values for 1 hour (Fig. 2). WebConditions optimum for the assay of alkaline phosphatase of marine pseudomonad B-16 (ATCC 19855) and for maintaining the activity of the enzyme have been determined. The pH for optimal activity of the cell-bound enzyme was 9.0, whereas that for the enzyme after its release from the cells exceeded 9.4.
WebThey fit with my prediction that the optimum pH for a Phosphate enzyme is around pH 3-5, and therefore we can say that it requires a more acidic pH than an alkaline one. WebMay 18, 1973 · With bicarbonate buffer, the maximum activity at 55 mM was about ten times that at 0.55 mM (Fig. i). With bone alkaline phosphatase, a similar pattern was observed, the optimum substrate concentration at pH 10.5 being lower when methyl aminopropanol-HCl was 2 SKILLEN, HARRISON used as buffer.
WebPMID: 8467238 Abstract The activity of rat liver alkaline phosphatase (ALP) was studied at physiological pH, using para-nitrophenyl phosphate (pNPP) as substrate. At this pH, the purified enzyme had optimal catalytic efficiency and its activity was maximal for the very low substrate concentrations.
Web3. With p-nitrophenylphosphate, pH-optimum and KM for the enzyme are 9.8 and 0.9 mM, respectively. 4. The enzyme was strongly inhibited by Sn4+, Fe3+ and Zn2+, whereas Mg2+ and Mn2+ were effective activators of the enzyme.
