In enzymology, a scytalone dehydratase (EC 4.2.1.94) is an enzyme that catalyzes the chemical reaction

scytalone 1,3,8-trihydroxynaphthalene + H2O

Hence, this enzyme has one substrate, scytalone, and two products, 1,3,8-trihydroxynaphthalene 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 scytalone 7,8-hydro-lyase (1,3,8-trihydroxynaphthalene-forming). This enzyme is also called scytalone 7,8-hydro-lyase.

Structural studies

As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes 1IDP, 1STD, 2STD, 3STD, 4STD, 5STD, 6STD, and 7STD.
