PoDPBT, a BAHD acyltransferase, catalyses the benzoylation in paeoniflorin biosynthesis in Paeonia ostii

PoDPBT, an O-benzoyltransferase belonging to the BAHD family, can catalyze the benzoylation of 8-debenzoylpaeoniflorin to paeoniflorin. PoDPBT is the first enzyme demonstrated to be involved in the modification stage of paeoniflorin biosynthesis. DFGGG, a new DFGWG-like motif, was revealed in the BAHD family. The transcriptome database provides a resource for further investigation of other enzyme genes involved in paeoniflorin biosynthesis.
