In enzymology, a sabinene-hydrate synthase (EC 4.2.3.11) is an enzyme that catalyzes the chemical reaction
- geranyl diphosphate + H2O 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.
