In biochemistry, an isomerase is an enzyme that catalyses the structural rearrangement of isomers. Isomerases thus catalyze reactions of the form
- A → B
Nomenclature
The names of isomerases are formed as "substrate isomerase" (for example, enoyl CoA isomerase), or as "substrate type of isomerase" (for example, phosphoglucomutase).
Classification
Isomerases have their own EC classification of enzymes: EC 5. Isomerases can be further classified into six subclasses:
