Inorganic pyrophosphatase in mineralizing hamster molars
- 19 Downloads
Inorganic pyrophosphatase contains both Zn2+ and Co2+ in the active center. The highest activity of the enzyme was obtained in the Zn2+ form. EDTA, diphosphonates and L-ascorbic acid are able to inhibit PPi-ase by complexing Zn2+ and Co2+.
