Isomerases

 

a class of enzymes comprising those that catalyze the intramolecular migration of various groups and the interconversion reactions of various isomers.

Isomerases catalyzing the interconversion of stereoisomers are called racemases or epimerases according to the number of centers of asymmetry in the substrate molecule. The isomerases also include cis-trans-isomerases, intramolecular oxidoreductases, intramolecular transferases, and intramolecular lyases. Sometimes the enzymes that catalyze the transfer of a group from one part of a molecule to another are called mutases.
