| Abstract: | Embryos of the sea urchin Strongylocentrotus intermedius have been found to contain o-glycosyl hydrolases: highly active 1,3-β-D-glucanase and β-D-mannosidase as well as a lower activity of β-D-glucosidase and β-D-galactosidase. Dynamics of changes of the enzyme activities has been studied at various stages of the sea urchin development. There has also been studied effects of some substances (natural fucoidans, β-1.3; 1.6-glucans formed by enzymatic synthesis as well as protein inhibitor of marine mollusc endo-1,3-β-D-glucanases) on development of the embryos and biosynthesis of 1,3-β-D-glucanase and α-D-mannosidase. |
