EC 2.4.1.168     
Accepted name: xyloglucan 4-glucosyltransferase
Reaction: Transfers a β-D-glucosyl residue from UDP-glucose on to a glucose residue in xyloglucan, forming a β-(1→4)-D-glucosyl-D-glucose linkage
Other name(s): uridine diphosphoglucose-xyloglucan 4β-glucosyltransferase; xyloglucan 4β-D-glucosyltransferase; xyloglucan glucosyltransferase; UDP-glucose:xyloglucan 1,4-β-D-glucosyltransferase
Systematic name: UDP-glucose:xyloglucan 4-β-D-glucosyltransferase
Comments: In association with EC 2.4.2.39 (xyloglucan 6-xylosyltransferase), this enzyme brings about the synthesis of xyloglucan; concurrent transfers of glucose and xylose are essential for this synthesis. Not identical with EC 2.4.1.12 cellulose synthase (UDP-forming).
