- acetyl-CoA + taxa-4(20),11-dien-5alpha-ol CoA + taxa-4(20),11-dien-5alpha-yl acetate
Thus, the two substrates of this enzyme are acetyl-CoA and taxa-4(20),11-dien-5alpha-ol, whereas its two products are CoA and taxa-4(20),11-dien-5alpha-yl acetate.
This enzyme participates in diterpenoid biosynthesis.
Nomenclature edit
This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:taxa-4(20),11-dien-5alpha-ol O-acetyltransferase. Other names in common use include acetyl coenzyme A:taxa-4(20),11(12)-dien-5alpha-ol O-acetyl, and transferase.
