| UDP-D-xylose + xylotetraose | 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 | Populus trichocarpa | ? | - |

| malfunction | microsomes from transgenic tobacco BY2 cells coexpressing PtrGT43B and PtrGT43C exhibit a high XylT activity capable of generating beta-(1,4)-linked xylooligosaccharides, whereas little XylT activity is detected in microsomes with expression of PtrGT43B or PtrGT43C alone | Populus trichocarpa |
| physiological function | PtrGT43B and PtrGT43C, are xylan XylTs involved in wood formation | Populus trichocarpa |
