Oviduktin (EC 3.4.21.120, oviduktalna proteaza) je enzim.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Preferentno razlaganje u Gly-Ser-Arg373- poziciji glikoproteina gp43 u ljuski jaja žabe Xenopus laevis, čime se formira gp41
Ljuska jajeta južnoafričke žabe (Xenopus laevis) se modifikuje tokom tranzita jajeta kroz jajovode, čime se kora menja iz neoplodive forme u oplodivu. Deo tog procesa je konverzija glikoproteina gp43 u gp41 posredstvom ovog enzima.
