Background and Purpose: Alkaline Phosphatase (EC: 22.214.171.124) is synthesized by kidney, liver, bone, Intestine and placenta. This enzyme is a glycoprotein and dimmer 4 Zn+2 and Mn+2 in each dimmer. It hydrolyzes mono ester phosphate to organic compound and phosphate_in alkaline medium. The purpose of this research is to compare this enzyme with placental alkaline phosphatase.
Methods and Materials: Human Molehydatiform was purified by folds of precipitation of bybutanol, acetone, Amoniumm sulphate, Sephadex G200, affinity chromatography and preparative electrophoresis.
Results: Human Molehydatiform was purified 611.8 times. We obtained specific activity, optimum temperature and optimum Ph equaling to 611.8 U/mg, 40 centigrade degrees and 10.4 respectively.
Conclusion: Purified Human Molehydatiform Alkalie phosphatase is different from Human placental Alkaline phosphatase due to optimum pH and optimum temperature.
