Structure of isomerases
Like all enzymes, isomerases are proteins which have an active site for the enzyme reaction and a target molecule recognition site which gives the reaction its specificity.
Function of the isomerases
The isomerases generally catalyse rearrangements of functional groups of the same molecule. There are many types of isomerases depending on the type of reaction they catalyse (racemases, cis-trans isomerases, lyases, transferases and intramolecular oxidoreductases …).
Isomers are molecules with the same basic chemical formula but their groups are not all arranged in the same way. © DR
