ID 2.4.2.39 DE xyloglucan 6-xylosyltransferase. AN uridine diphosphoxylose-xyloglucan 6alpha-xylosyltransferase. AN xyloglucan 6-alpha-D-xylosyltransferase. CA Transfers an alpha-D-xylosyl residue from UDP-D-xylose to a glucose CA residue in xyloglucan, forming an alpha-(1->6)-D-xylosyl-D-glucose CA linkage. CC -!- In association with EC 2.4.1.168 this enzyme brings about the CC synthesis of xyloglucan. CC -!- Concurrent transfers of glucose and xylose are necessary for this CC synthesis. CC -!- Formerly EC 2.4.1.169. DR Q9LZJ3, XXT1_ARATH ; A2XFP3, XXT1_ORYSI ; Q10MQ0, XXT1_ORYSJ ; DR O22775, XXT2_ARATH ; Q9LF80, XXT3_ARATH ; Q9M9U0, XXT4_ARATH ; DR Q9CA75, XXT5_ARATH ; //
