In enzymology, a glycerol dehydratase (EC 4.2.1.30) is an enzyme that catalyzes the chemical reaction

glycerol 3-hydroxypropanal + H2O

Hence, this enzyme has one substrate, glycerol, and two products, 3-hydroxypropanal 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 glycerol hydro-lyase (3-hydroxypropanol-forming). Other names in common use include glycerol dehydrase, and glycerol hydro-lyase. This enzyme participates in glycerolipid metabolism. It employs one cofactor, cobalamin.

Structural studies[edit]

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1IWP and 1MMF.
