Choriolysin H (EC 3.4.24.67, teleost hatching enzyme (component), high choriolytic enzyme (HCE)) is an enzyme.[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- Hydrolysis of the inner layer of fish egg envelope. Also hydrolysis of casein and small molecule substrates such as succinyl-Leu-Leu-Val-Tyr-7-(4-methyl)coumarylamide
This enzyme is present in teleost fish Oryzias latipes.
