They can be found in many places including the mitochondria, peroxisome and cytosol. There are more than 150 different dehydratase enzymes that are classified into four groups. Dehydratases can act on hydroxyacyl-CoA with or without cofactors, and some have a metal and non-metal cluster act as their active site.
