microsomes isolated from transgenic BY2 cells are tested for XylT activity using xylotetraose (Xyl4) as an acceptor and UDP-xylose as a donor. XylT activity can not use the xylose monomer as an acceptor. Xylosyl residues are readily transferred onto xylooligomers ranging from 2 to 6 residues, resulting in the production of xylooligosaccharides with up to 11 xylosyl residues
