We are aiming to switch to the new UniProt website on Monday, May 9. Please explore and share your feedback.
Take me to the new website.
UniProtKB - P9WEW2 (STS1_STEHR)
Protein
Delta(6)-protoilludene synthase STEHIDRAFT_73029
Gene
STEHIDRAFT_73029
Organism
Stereum hirsutum (strain FP-91666) (White-rot fungus)
Status
Functioni
Terpene cyclase that catalyzes the cyclization of farnesyl diphosphate (FPP) to delta6-protoilludene (PubMed:24166732, PubMed:26239156).
In presence of Ca2+, a significant switch from 1,11 to a dual 1,11/1,10 cyclization occurs, producing beta-elemene as the major product, with lower levels of delta6-protoilludene and (E)-beta-caryophyllene, and traces of beta-selinene and alpha-selinene (PubMed:26239156).

- EC:4.2.3.1352 PublicationsThis reaction proceeds in the forward2 Publications direction.
- EC:4.2.3.1981 PublicationThis reaction proceeds in the forward1 Publication direction.
Cofactori
Mg2+1 Publication, Mn2+1 Publication, Ca2+1 Publication, Ni2+1 Publication, Co2+1 PublicationNote: Mg2+ and Mn2+ are more tightly associated with the active site motifs (D(D/E)XX(D/E) and NSE) and thus lead to more efficient removal of PPi (PubMed:26239156). In the presence of Co2+ and Ni2+ the activity is retained and delta(6)-protoilludene is the major volatile sesquiterpene produced (PubMed:26239156). In the presence of Ca2+, the major sesquiterpene produced switches to beta-elemene (PubMed:26239156).1 Publication
Activity regulationi
Ca2+ switches the cyclization mechanism of delta6-protoilludene synthase from 1,11 to 1,10 cyclization which leads to the production of beta-elemene.1 Publication
