Abstract
ATP and 5-Br-4-Cl-indoxyl phosphate were used as substrates for spectrophotometric measurement of phosphatase activity in partly mineralized bovine enamel. MgCl2, CaCl2, NaCl, and KCl were used as moderators of the enzyme activities. It is concluded that at least two phosphatases, active at alkaline pH, are present in the immature enamel matrix.
摘要
ATP和5-溴-4-氯吲哚酚磷酸酯被用作底物，用于分光光度法测定部分矿化牛牙釉质中的磷酸酶活性。MgCl2、CaCl2、NaCl和KCl被用作酶活性的调节剂。得出的结论是，在未成熟的牙釉质基质中至少存在两种在碱性pH下具有活性的磷酸酶。
