• Plasma membrane fractions were prepared from the embryos of sea urchin, Hemicentrotus pulcherrimus, at one-cell, hatched biastula and prism stages. The plasma membrane fractions, which were essentially free from yolk and other organelles as assessed by electron microscopy and which possessed 5'-nucleotidase activity, showed a considerable activity of adenylate cyclase that was insensitive or only weakly sensitive to fluoride ions. Adenylate cyclase activity was also found in the fractions other than plasma membranes, and the enzyme activities in these fractions were markedly stimulated by fluoride ions. Contrary to a previous report, adenylate cyclase activity in sea urchin embryos increased with development at least up to prism stage. A possible lack of a regulatory subunit from adenylate cyclase system in plasma membranes was discussed.
