Michaelis Constants

The Michaelis constants and the rates at high substrate concentration for the system p-nitrophenyl phosphate – intestinal alkaline phosphatase have been measured at 15.3 °C and 24.4 °C from pH 7.5 to pH 10.4.The experimental data can be interpreted as indicating the presence of three acid groups in the active center of the enzyme. The observed pK of ionization of these groups are 9.02, 8.39, and 7.65 at 15.3 °C, and 9.75, 8.42, and 7.62 at 24.4 °C.These data stress the importance of electrostatic interactions between the groups in the active center and the rest of the enzyme molecule. A heat of ionization of 6 to 7 kcal/mole is attributed to each of these groups. At least one active group of the enzyme would be a thiol function and the other ones imidazole or thiol.
