Dehydratase

From Wikipedia, the free encyclopedia
Serine dehydratase is an example of a dehydratase. It utilizes PLP as a cofactor.

Dehydratases are a group of lyase enzymes that form double and triple bonds in a substrate through the removal of water.[1] They can be found in many places including the mitochondria, peroxisome and cytosol.[2] There are more than 150 different dehydratase enzymes[3] 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.[citation needed]

Pathology

[edit]

A dehydratase 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.[4]

Examples

Common dehydratases include:
