ExplorEnz-The Enzyme Database
It is the definitive list of 6,400, produced by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB). Each entry has accepted name, synonyms of the enzyme, cross references to BRENDA, KEGG, MetaCyc and CAS registry number, literature reference and comments on cofactors etc. The search function allows you to find EC no. by a common enzyme name. Use the enzyme list as an Enzyme Nomenclature Book.
ExplorEnz is designed, developed and maintained for the IUBMB by Andrew McDonald (School of Biochemistry & Immunology, Trinity College, Dublin 2, Ireland)
