REACTION DIAGRAM
baccatin III + 3-phenylisoserinoyl-CoA
? + coenzyme A
selective for 3-amino-3-phenylpropanoyl-CoA esters with a preference for beta-phenylalanoyl-CoA over 3-phenylisoserinoyl-CoA. Activity with 3-phenylisoserinoyl-CoA is 40% of the activity with beta-phenylalanoyl-CoA. alpha-Phenylalanoyl-CoA and N-benzoyl phenylisoserinoyl-CoA are not productive acyl donors

baccatin III + 3-amino-3-phenylpropanoyl-CoA
3'-N-debenzoyl-2'-deoxytaxol + coenzyme A
selective for 3-amino-3-phenylpropanoyl-CoA esters with a preference for beta-phenylalanoyl-CoA over 3-phenylisoserinoyl-CoA. alpha-Phenylalanoyl-CoA and N-benzoyl phenylisoserinoyl-CoA are not productive acyl donors
this enzymatic product is converted to 2'-deoxytaxol by chemical N-benzoylation, and the identity of this derivative is confirmed by spectrometric analyses
