This family includes a number of transferase enzymes. These include anthranilate N-hydroxycinnamoyl/benzoyltransferase that catalyzes the first committed reaction of phytoalexin biosynthesis. Deacetylvindoline 4-O-acetyltransferase EC:22.214.171.124 catalyzes the last step in vindoline biosynthesis is also a member of this family. The motif HXXXD is probably part of the active site. The family also includes trichothecene 3-O-acetyltransferase.
