Accepted name: taxadien-5α-ol O-acetyltransferase
Reaction: acetyl-CoA + taxa-4(20),11-dien-5α-ol = CoA + taxa-4(20),11-dien-5α-yl acetate
Other name(s): acetyl coenzyme A:taxa-4(20),11(12)-dien-5α-ol O-acetyl transferase
Systematic name: acetyl-CoA:taxa-4(20),11-dien-5α-ol O-acetyltransferase
Comments: This is the third enzyme in the biosynthesis of the diterpenoid antineoplastic drug taxol (paclitaxel), which is widely used in the treatment of carcinomas, sarcomas and melanomas.
