ID 2.4.1.168 DE xyloglucan 4-glucosyltransferase. CA Transfers a beta-D-glucosyl residue from UDP-glucose on to a glucose CA residue in xyloglucan, forming a beta-(1->4)-D-glucosyl-D-glucose CA linkage. CC -!- In association with EC 2.4.2.39, brings about the synthesis of CC xyloglucan. CC -!- Concurrent transfers of glucose and xylose are essential for this CC synthesis. CC -!- Not identical with EC 2.4.1.12. //
