It is primarily based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB) and it describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided [More details / …

The EC inventory published below is a copy as received from the JRC in 2008 on the founding of ECHA. It is comprised of the following lists: EINECS (European INventory of Existing Commercial chemical Substances) as published in O.J. C 146A, 15.6.1990.

The check digit for the EC or list number is calculated using the ISBN method in both numerical and alphanumerical format. For calculation purposes, the letter in a list number is given a numerical value: A=10, B=11 etc. Letters I, L and O are not used in list numbers to avoid potential confusion with numbers 0 and 1.

When the KEGG database was initiated in 1995, the EC number was used as a primary identifier for reconstructing the metabolic pathway from the complete genome. This was accomplished by drawing metabolic pathway maps with EC number nodes and by annotating enzyme genes in the genome with EC numbers.

2024年1月30日 · What’s an EC Number? The Enzyme Commission (EC) number is a nomenclature system based on the chemical reactions that these proteins catalyze. It was developed by the International Union of Biochemistry and Molecular Biology (IUBMB) and consists of a numerical classification scheme where each number is associated with an …

2024年6月25日 · The EC classification groups enzymes that perform the same or related enzymatic functions. You can use the EC browser to explore enzymes that have similar functions, shape of enzyme and/or arrangements of amino acids performing the enzyme reaction.

2024年11月20日 · An EC number is group of four numbers separated by periods in papers discussing enzymes…something like this: EC 1.1.2.1. But do you know what these numbers mean? Or where they came from?

The nomenclature developed by the International Union of Biochemistry and Molecular Biology has something called EC numbers where each enzyme is preceded by EC. The first number in this series classifies this enzyme on the basis of its mechanism.
