Isomerase

Wikipedia
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 are classified as EC 5 in the EC number classification of enzymes. 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)
