Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Glutamyl endopeptidase was tested for aquatic toxicity, including read-across studies.
Fish: Glutamyl endopeptidase has not been tested in fish, however, a similar enzyme - subtilisin - has been tested in rainbow trout for 96 hours. The 96-hour LC50 value for subtilisin was nominally 17.7 mg TOS/L, with 95% confidence limits of 13.3 and 23.5 mg TOS/L. Based on the initial measured levels, the 96-hour LC50 was 14.6 mg TOS/L (95% confidence limits, 10.6 and 19.9 mg TOS/L) corresponding to 8.2 mg aep/L. The no-observed-effect concentration (NOEC) was not clearly identified during the definitive test but based on the findings of a range finding test, the NOEC was 10 mg TOS/L (nominal) corresponding to 4.6 mg aep/L.
Invertebrates: Under the conditions of the test, testing of glutamyl endopeptidase batch PPA27269 to Daphnia magna revealed an 48h EC50 value of 5 mg TOS/L (0.7 mg aep/L). The NOEC (48h) was determined to be > 4.6 mg/L (0.66 mg aep/L).
Another similar enzyme – subtilisin – was tested using Daphnia magna. The EC value was 0.306 mg TOS/L (0.17 mg aep/L), and NOEC was 0.066 mg TOS/L (36.7 µg aep/L).
Algae: Glutamyl endopeptidase batch PPA 27269 was tested with Pseudokirchneriella subcapitata. It inhibited algal growth at 10 mg TOS/L, whereas no inhibitory effect was detected at lower concentrations. The inhibitory effect at 10 mg TOS/L was below 50% and thus no ErC values could be determined (and must be above 10 mg TOS/L (14.3 mg aep/L). The NOEC was determined to be 1 mg TOS/L (0.14 mg aep/L).
Another similar enzyme - subtilisin – was tested with Pseudokirchneriella subcapitata. The 72-hour ErC50 was 1.48 mg TOS/L corresponding to 830 µg aep/L. The NOEC was 0.566 mg TOS/L.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
