3.4.24.66

Accepted name:

choriolysin L

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

Other name(s):

teleost hatching enzyme (component); low choriolytic enzyme (LCE)

Comments:

Known from the teleost fish Oryzias latipes (medaka). Efficient dissolution of the egg membrane requires concerted action with choriolysin H. A 24 kDa peptidase family M12 (astacin family)
