Classification
Isomerases have their own EC classification of enzymes: EC 5. Isomerases can be further classified into six subclasses:
- EC 5.1 includes enzymes that catalyze racemization (racemases) and epimerization (epimerases)
- EC 5.2 includes enzymes that catalyze the isomerization of geometric isomers (cis-trans isomerases)
- EC 5.3 includes intramolecular oxidoreductases
- EC 5.4 includes intramolecular transferases (mutases)
- EC 5.5 includes intramolecular lyases
- EC 5.99 includes other isomerases (including topoisomerases)
