Sabinene-hydrate synthase

From Wikipedia, the free encyclopedia

In enzymology, a sabinene-hydrate synthase (EC 4.2.3.11) is an enzyme that catalyzes the chemical reaction

geranyl diphosphate + H₂O $\rightleftharpoons$ sabinene hydrate + diphosphate

Thus, the two substrates of this enzyme are geranyl diphosphate and H₂O, whereas its two products are sabinene hydrate and diphosphate.

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is geranyl-diphosphate diphosphate-lyase (cyclizing, sabinene-hydrate-forming). This enzyme is also called sabinene hydrate cyclase. This enzyme participates in monoterpenoid biosynthesis.
