== Function ==
[https://www.uniprot.org/uniprot/SEDS_STRE2 SEDS_STRE2] Catalyzes the conversion of (2E,6E)-farnesyl diphosphate (FPP) to yield the bicyclic sesquiterpene selina-4(15),7(11)-diene via a 1,10-cyclization, which requires the abstraction of the pyrophosphate from FPP leading to a (E,E)-germacradienyl cation (PubMed:23307484, PubMed:24890698). The only accepted substrate is (2E,6E)-farnesyl diphosphate (FPP) (PubMed:23307484, PubMed:24890698).<ref>PMID:23307484</ref> <ref>PMID:24890698</ref>
