Question

What is the basis of nomenclature of enzymes?

Answer 1

Enzymes are classified into six different groups according to the reaction being catalyzed. Thenomenclature was determined by theEnzyme Commission in 1961 (with the latest update having occurred in 1992), hence all enzymes are assigned an “EC” number.

Answer 2

Except for some of the originally studied enzymes such as pepsin, rennin, and trypsin, most enzyme names end in "ase". The International Union of Biochemistry (I.U.B.) initiated standards of enzyme nomenclature which recommend that enzyme names indicate both the substrate acted upon and the type of reaction catalyzed.
