EC 2.4.2.39     
Accepted name: xyloglucan 6-xylosyltransferase
Reaction: Transfers an α-D-xylosyl residue from UDP-D-xylose to a glucose residue in xyloglucan, forming an α-(1→6)-D-xylosyl-D-glucose linkage
Other name(s): uridine diphosphoxylose-xyloglucan 6α-xylosyltransferase; xyloglucan 6-α-D-xylosyltransferase; UDP-D-xylose:xyloglucan 1,6-α-D-xylosyltransferase
Systematic name: UDP-D-xylose:xyloglucan 6-α-D-xylosyltransferase
Comments: In association with EC 2.4.1.168 (xyloglucan 4-glucosyltransferase), this enzyme brings about the synthesis of xyloglucan; concurrent transfers of glucose and xylose are necessary for this synthesis.
