label: xyloglucan:xyloglucosyl transferase activity
label_lc: xyloglucan:xyloglucosyl transferase activity
description: "Catalysis of the cleavage of a beta-(1->4) bond in the backbone of a xyloglucan and transfers the xyloglucanyl segment on to O-4 of the non-reducing terminal glucose residue of an acceptor, which can be a xyloglucan or an oligosaccharide of xyloglucan."
