Oviductin
From Wikipedia, the free encyclopedia
Oviductin (EC 3.4.21.120, oviductal protease) is an enzyme found in the Japanese toad (Bufo japonicus) and in the African clawed frog (Xenopus laevis).[1][2][3] Ovulated coelomic egg cells are not fertilisable in these species until they pass through the oviduct, where Oviductin is located.[4] Oviductin catalyses the following chemical reaction in Xenopus laevis:
- Preferential cleavage at Gly-Ser-Arg373- of glycoprotein gp43 in the coelemic egg envelope to yield gp41.
