About ExplorEnz

ExplorEnz contains the approved International Union of Biochemistry and Molecular Biology (IUBMB) Enzyme nomenclature and classification list. It was developed at Trinity College Dublin in 2005 as a new way to access the data of the IUBMB Enzyme Nomenclature List. The data, which are stored in a MySQL database, preserve the formatting of chemical names according to IUPAC standards. A simple, easy to use, web-based query interface is provided (Search), along with an advanced search engine for more complex queries (Advanced Search).

ExplorEnz is developed and maintained by Andrew McDonald.ORCID iD icon
