10-deacetylbaccatin III 10-O-acetyltransferase () is an enzyme that catalyzes the chemical reaction
The enzyme completes the biosynthesis of baccatin III by transferring an acetyl group from acetyl-CoA to the intermediate 10-deacetylbaccatin, giving coenzyme A as a byproduct. It was isolated from yew trees (Genera Taxus) and the gene was expressed in Escherichia coli to allow characterisation. It has also been expressed in the mushroom Flammulina velutipes.
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:taxan-10beta-ol O-acetyltransferase.
