In enzymology, a (+)-delta-cadinene synthase (EC 4.2.3.13) is an enzyme that catalyzes the chemical reaction

2-trans,6-trans-farnesyl diphosphate $\rightleftharpoons$ (+)-delta-cadinene + diphosphate

Hence, this enzyme has one substrate, 2-trans,6-trans-farnesyl diphosphate, and two products, (+)-delta-cadinene 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 2-trans,6-trans-farnesyl-diphosphate diphosphate-lyase (cyclizing, (+)-delta-cadinene-forming). This enzyme participates in terpenoid biosynthesis. It employs one cofactor, magnesium.
