In biochemistry, an isomerase is an enzyme that catalyses the interconversion of polymers. Isomerases thus catalyze reactions of the form
- A → B
Additional recommended knowledge
The names of isomerases are formed as "substrate isomerase" (for example, enoyl CoA isomerase), or as "substrate type of isomerase" (for example, phosphoglucomutase).
Isomerases are classified as EC 5 in the EC number classification of enzymes. Isomerases can be further classified into six subclasses:
- EC 5 Introduction from the Department of Chemistry at Queen Mary, University of London
|Intramolecular oxidoreductases isomerases (EC 5.3)|
|5.3.1 - Aldoses/Ketoses||Triosephosphate isomerase - Phosphopentose isomerase - Mannose phosphate isomerase - Glucose isomerase|
|5.3.3 - C=C||Isopentenyl-diphosphate delta isomerase - Enoyl CoA isomerase|
|5.3.4 - S-S||Protein disulfide isomerase (PDIA3)|
|5.3.99 - other||Prostaglandin D2 synthase - Prostaglandin E synthase - Prostacyclin synthase - Thromboxane-A synthase|
|Isomerase: mutases (EC 5.4)|
|5.4.2 Phosphomutases||Phosphoglycerate mutase - Bisphosphoglycerate mutase - Phosphoglucomutase|
|5.4.99 Other groups||Methylmalonyl-CoA mutase - Lanosterol synthase|
