Cleaves and religates xyloglucan polymers, an essential constituent of the primary cell wall, and thereby participates in cell wall construction of growing tissues (By similarity).CATALYTIC ACTIVITY:Breaks 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.TISSUE SPECIFICITY:Predominantly expressed in the phloem fibers of growing internodes. Weakly or not expressed in the xylem. In the internode, it is expressed closer to the bottom of the internode compared to XTHA.INDUCTION:Up-regulated by indole-3-acetic acid (IAA). Effect of IAA is not affected by mannitol. Not up-regulated by fusicoccin.PTM:Contains at least one intrachain disulfide bond essential for its enzymatic activity (By similarity).SIMILARITY:Belongs to the glycosyl hydrolase 16 family. XTH group 1 subfamily."
