Aconitate hydratase is the enzyme which performs an isomerization reaction carried out by dehydration and hydration steps.
What is an Enzyme?
These are proteins which serves as biological catalyst thereby accelerating the rate of chemical reaction.
This enzyme catalyses the stereo-specific isomerization of citrate to isocitrate and contains a 4Fe-4S cluster that is involved in substrate binding.
