List of EC numbers (EC 4)

From Wikipedia, the free encyclopedia

This list contains a list of EC numbers for the fourth group, EC 4, lyases, 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] The database is developed and maintained by Andrew McDonald.[2]
