Protein

Taxadiene synthase

Gene

TDC1

Organism
Taxus brevifolia (Pacific yew)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the cyclization of the ubiquitous isoprenoid intermediate geranylgeranyl diphosphate to taxa-4,11-diene, the parent olefin with a taxane skeleton.

Catalytic activityi

Geranylgeranyl diphosphate = taxa-4,11-diene + diphosphate.
