Ph optimum alkalische phosphatase
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. 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. Seal alkaline phosphatase was slightly inhibited by high concentrations of Ca2+ and Cr3+. 5.
