3.4.21.120 | 55 kDa glycoprotein + H2O |
the oviductal protease selectively hydrolyzes in vitro the 84 kDa and the 55 kDa glycoproteins of the coelomic envelope |

3.4.21.120 | gp43 + H2O |
oviductin alone is the oviductal factor responsible for converting the egg envelope to a sperm-penetrable form, via an increase in sperm binding. gp43 processing is the only requirement for envelope conversion |

3.4.21.120 | gp43 + H2O |
preferential cleavage at Gly-Ser-Arg373-/-glycoprotein gp43 in Xenopus laevis coelemic egg envelope to yield gp41. Processing of gp43 causes physical changes in the egg envelope which occurs during egg transit through the oxiduct |

it is proposed that hamster oviductin is a mucin-type glycoprotein which might act as a protective secretion influencing the first steps of the reproductive process necessary for the normal triggering of fertilization and early embryonic development |
