To elucidate the progressive disappearance of 25 kDa amelogenin occurring in a narrow space near the surface of enamel, the alkaline soluble fraction which contained 80% of the total proteins was extracted from a newly formed porcine enamel. When this fraction was incubated with the addition of Ca ions in an in vitro system, the degradation of the coexisting amelogenin and enamelin occurred without activation during the incubation period.
