Terpene synthase that catalyzes the conversion of (2E,6E)-farnesyl diphosphate (FPP) into sesquiterpenes which are important for fungi-environment interactions (PubMed:31239482). Produces a mixture consisting of 9 sesquiterpenes including gamma-cadinene, delta-cadinene, alpha-cadinene, alpha-cadinol, beta-elemene, (E)-beta-caryophyllene, germacrene D, gamma-muurolene and an unidentified oxygen-containing sesquiterpene (PubMed:31239482). Binds 3 Mg(2+) ions per subunit. The Asp-Asp-Xaa-Xaa-Xaa-Asp (DDXXXD) motif is important for the catalytic activity, presumably through binding to Mg(2+). Belongs to the terpene synthase family.
