SSDG_02809

Gene
SSDG_02809
Protein
Selina-4(15),7(11)-diene synthase ((2E,6E)-farnesyl diphosphate cyclizing)
Organism
Streptomyces pristinaespiralis (strain ATCC 25486 / DSM 40338 / CBS 914.69 / JCM 4507 / NBRC 13074 / NRRL 2958 / 5647)
Length
365 amino acids
Function
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).
Similarity
Belongs to the terpene synthase family.
