Protein

Shionone synthase

Gene

SHS1

Organism
Aster tataricus (Tartarian aster)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Oxidosqualene cyclase involved in the production of shionone, a triterpenoid with a rare 6/6/6/6 tetracyclic skeleton and a C-3 carbonyl carbon. Produces also small amounts of beta-amyrin, friedelin, dammara-20,24-dienol, and 4-epishionone.1 Publication

Catalytic activityi

(3S)-2,3-epoxy-2,3-dihydrosqualene = shionone.1 Publication
