Evaluating the article Dehydratase Dehydratases are a group of lyase enzymes that form double and triple bonds in a substrate through the removal of water. 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.
 * 1) There are no citations in this article so there is no way of knowing whether or not the information is accurate or where it came from.
 * 2) The only thing the article provides besides a definition is that there are four kinds of dehydratases with a brief description of what they act on. It does not elaborate on where the dehydratases are found nor any structural differences.
 * 3) It also mentions a lot of jargon that could be linked to other wikipedia pages.
 * 4) There is no bias or view point taken with this article.
 * 5) It does not provide any reference to the discovery of this enzyme nor dates to put the information in perspective.

A dehyratase deficiency in the body can lead to a less severe condition of hyperphenylalaninemia, which involves an over presence of phenylalanine in the blood. It is caused by a genetic recessive disorder in the autosomal DNA.

Common dehydratases include:

Delta-aminolevulinic acid dehydratase is found in blood and is involved in the production of the heme group of globins. People exposed to lead will have a decrease in ADA-D activity.

Serine dehydratase is mostly found in the liver and catalyzes the reaction of turning serine into pyruvate and ammonia. In a diet of increased protein, the activity of serine dehydratase is increased.

Arogenate dehydratase is found mostly in the chloroplasts of higher plants. It catalyzes the reaction of turning L-arogenate into L-phenylalanine.
