RT   side-chain N-benzoyltransferase from Taxus.";

CC   -!- FUNCTION: Catalyzes the stereoselective coupling of the surrogate
CC       substrate N-debenzoyl-(3'RS)-2'-deoxytaxol with benzoyl-CoA to form
CC       predominantly one 3'-epimer of 2'-deoxytaxol (PubMed:12089320). This
CC       enzymatic reaction constitutes the final acylation in the taxol
CC       biosynthetic pathway (PubMed:12089320). {ECO:0000269|PubMed:12089320}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3'-N-debenzoyltaxol + benzoyl-CoA = CoA + H(+) + taxol;

CC         Evidence={ECO:0000269|PubMed:12089320};
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=0.45 mM for 3'-N-debenzoyltaxol {ECO:0000269|PubMed:12089320};
CC         KM=0.41 mM for benzoyl-CoA {ECO:0000269|PubMed:12089320};
CC       pH dependence:
CC         Optimum pH is 8.0. {ECO:0000269|PubMed:12089320};
CC   -!- PATHWAY: Alkaloid biosynthesis; taxol biosynthesis. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the plant acyltransferase family. {ECO:0000305}.
