The Enzyme Nomenclature (also known as the Enzyme Commission Code) is a species-agnostic controlled vocabulary for specific enzymes and an associated hierarchical classification into 7 main categories. The Enzyme Nomenclature is maintained by the [Nomenclature Committee](https://iubmb.org/about/committees/nomenclature-committee/) of the International Union of Biochemistry and Molecular Biology (IUBMB). A detailed history of the nomenclature since the 1950s can be found [here](https://iubmb.qmul.ac.uk/enzyme/history.html). There are few notable resources providing access to the Enzyme Nomenclature: <table class="table table-striped"><thead><tr><th>Website</th><th>Homepage</td><th>Notes</td></tr></thead><tbody><tr><td>ExplorEnz</td><td><a href="https://www.enzyme-database.org">https://www.enzyme-database.org</a></td><td>This is the resource officially recommended by IUBMB</td></tr><tr><td>IUBMB (via by Queen Mary)</td><td><a href="https://iubmb.qmul.ac.uk/enzyme">https://iubmb.qmul.ac.uk/enzyme</a></td><td>This is a web-based version of the <a href="https://archive.org/details/enzymenomenclatu0000inte_d6c2">1992 publication</a>.</td></tr><tr><td>IntEnz</td><td><a href="https://www.ebi.ac.uk/intenz">https://www.ebi.ac.uk/intenz</a></td><td>Shutdown in 2024</td></tr><tr><td>ExPaSy</td><td><a href="https://enzyme.expasy.org">https://enzyme.expasy.org</a></td></tr><tr><td>EnzymePortal</td><td><a href="https://www.ebi.ac.uk/enzymeportal">https://www.ebi.ac.uk/enzymeportal</a></td><td></td></tr></tbody></table>

The Electron Microscopy (EM) Glossary is a widespread community effort to harmonize terminology in the electron and ion microscopies.
