Nucleotide phosphatase in Strongylocentrotus purpuratus eggs. 3. Multiple enzymatic activities in mature and immature eggs.

On the basis of reaction patterns of eggs treated with activators and inhibitors and selected reactivating agents, there are at least three separate nucleotide phosphatase activities identifiable in maturing sea urchin eggs. Of these activities, the first two are sensitive to K + and Mg + +, respectively. The third activity is enhanced by both Na + and Ca + + and may represent two separate enzymes. These enzymatic activities are associated with different localizations and lead to a hypothesis of changing enzymatic patterns and localizations during the course of oogenesis.
