INORGANIC PYROPHOSPHATASE FROM POLYPORUS CIRCINATUS

[摘要] The inorganic pyrophosphatase from Polyporus circinatus was partially purified. The enzyme was active at PH 7.0 and 8.4. Optimal conditions for hydrolysis of pyrophosphate was observed at 52°. The enzyme was specific for inorganic pyrophosphate and was dependent on Mg2+. The Michaelis-Menten constant was 5.0×10-4M at 37° and 5.5×10-4M at 52°.
