dehydratase

 [de-hi´drah-tās]
any enzyme of the lyase class that catalyzes the removal of H2O, leaving double bonds (or adding groups to double bonds).

de·hy·dra·tase

(dē-hī'dră-tās),
A subclass of lyases (hydro-lyases) that remove H and OH as H2O from a substrate, leaving a double bond, or add a group to a double bond by the elimination of water from two substances to form a third; synthase is sometimes used when the synthetic aspect of the reaction is emphasized. Some trivial names of enzymes in this subclass bear the generic term hydratase, emphasizing the reverse reaction.

dehydratase

/de·hy·dra·tase/ (de-hi´drah-tās) a common name for a hydro-lyase.

dehydratase

(dē-hī′drə-tās′, -tāz′)

de·hy·dra·tase

(dē-hī'dră-tās)
A subclass (EC 4.2.1) of lyases (hydrolyases) that remove H and OH as H2O from a substrate, leaving a double bond, or add a group to a double bond by the elimination of water from two substances to form a third.

dehydratase
