These are the same filters already available on the v2 enzyme listing endpoint. ```bash curl -u sk_YOUR_SECRET_KEY: \ "https://$YOUR_DOMAIN.benchling.com/api/v3-beta/benchling/enzyme/items?name.anyOf=EcoRI,BamHI" ``` `Enzyme` is now an immutable domain object as part of the v3 beta stability requirements.
