The Enzyme Commission number (EC number) is a numerical classification scheme for enzymes, based on the chemical reactions they catalyze. [1] As a system of enzyme nomenclature , every EC number is associated with a recommended name for the corresponding enzyme-catalyzed reaction.
This list contains a list of sub-classes for the seventh group of Enzyme Commission numbers, EC 7, translocases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology. All official information is tabulated at the website of the committee. [1]
This list contains a list of EC numbers for the third group, EC 3, hydrolases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology.
This enzyme was already in the Enzyme List as EC 1.1.1.206, tropine dehydrogenase so EC 1.1.1.293 has been withdrawn at the public-review stage EC 1.1.1.294 : chlorophyll(ide) b reductase EC 1.1.1.295 : momilactone-A synthase
The International Union of Biochemistry and Molecular Biology have developed a nomenclature for enzymes, the EC numbers (for "Enzyme Commission"). Each enzyme is described by "EC" followed by a sequence of four numbers which represent the hierarchy of enzymatic activity (from very general to very specific). That is, the first number broadly ...
Enzymes are listed here by their classification in the International Union of Biochemistry and Molecular Biology's Enzyme Commission ... EC number Examples; EC 5.5.1.1:
EC 6.3.2.19: The ubiquitinylation process is now known to be performed by several enzymes in sequence, starting with EC 6.2.1.45 (ubiquitin-activating enzyme E1) and followed by several transfer reactions, including those of EC 2.3.2.23 (E2 ubiquitin-conjugating enzyme) and EC 2.3.2.27 (RING-type E3 ubiquitin transferase)
EC 2.5.1.64: The reaction that was attributed to this enzyme is now known to be catalysed by two separate enzymes: EC 2.2.1.9 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylic-acid synthase and EC 4.2.99.20 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate synthase; EC 2.5.1.65: O-phosphoserine sulfhydrylase
