Protein

Taraxerol synthase

Gene
N/A
Organism
Kalanchoe daigremontiana (Devil's backbone) (Bryophyllum daigremontianum)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Oxidosqualene cyclase that generates taraxerol, a triterpenoid product. Taraxerol is probably required to coat the leaf exterior as a defense compound against pathogens or herbivores.1 Publication

Catalytic activityi

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