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.
