Linalool dehydratase (EC 4.2.1.127, linalool hydro-lyase (myrcene-forming)) is an enzyme with systematic name (3S)-linalool hydro-lyase (myrcene-forming).^[1]^[2] This enzyme catalyses the following chemical reaction

\rightleftharpoons

myrcene + H₂O

In absence of oxygen this enzyme can also catalyse the isomerization of (3S)-linalool to geraniol.
