抄録

The envelope, chorion, of unfertilized eggs of medaka (Oryzias latipes) consists mainly of glycoprotein components, ZI-1,2 (74-76-kD) and ZI-3 (49-kD). During the chorion hardening after egg activation, all the components are polymerized by the action of transglutaminase responsible for γ-glutamyl-ε-lysine crosslink formation. Prior to the polymerization, ZI-1,2 are cleaved by an enzyme(s) released from egg to change into 58-62-kD components. We discuss the possibility that the limited degradation of ZI-1,2 promotes the polymerization of chorion components. Thus the chorion hardening reaction is catalyzed by a multiple enzyme system.
