3 hydroxyoctanoyl (acyl carrier protein) dehydratase

In enzymology, a 3-hydroxyoctanoyl-[acyl-carrier-protein] dehydratase (EC 4.2.1.59) is an enzyme that catalyzes the chemical reaction

(3R)-3-hydroxyoctanoyl-[acyl-carrier-protein] ⇌ oct-2-enoyl-[acyl-carrier-protein] + H₂O

Hence, this enzyme has one substrate, (3R)-3-hydroxyoctanoyl-(acyl-carrier-protein), and two products, [[oct-2-enoyl-[acyl-carrier-protein]]] and H₂O.

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is (3R)-3-hydroxyoctanoyl-[acyl-carrier-protein] hydro-lyase (oct-2-enoyl-[acyl-carrier protein]-forming). Other names in common use include D-3-hydroxyoctanoyl-[acyl carrier protein] dehydratase, D-3-hydroxyoctanoyl-acyl carrier protein dehydratase, beta-hydroxyoctanoyl-acyl carrier protein dehydrase, beta-hydroxyoctanoyl thioester dehydratase, beta-hydroxyoctanoyl-ACP-dehydrase, and (3R)-3-hydroxyoctanoyl-[acyl-carrier-protein] hydro-lyase.
