To investigate the molecular basis of the observed morphological and biological characteristics of coelomic egg envelopes (CE), vitelline envelopes (VE), and fertilization envelopes (FE) of Xenopus laevis eggs, envelopes were radioiodinated under a variety of conditions: in situ, isolated and intact

Xenopus laevis coelomic (body cavity) eggs are not fertilizable until they pass through the pars recta oviduct. A secreted pars recta oviductal protease with trypsin-like activity, oviductin, selectively hydrolyzes egg envelope glycoprotein gp43 to gp41; this limited proteolysis is believed to rende
## Abstract The acrosome reaction of newt sperm is induced at the surface of egg jelly and the acrosomeβreacted sperm acquire the ability to bind to the vitelline envelope. However, because the substance that induces the acrosome reaction has not been identified, the mechanism by which the acrosome
