Cleaves and religates xyloglucan polymers, an essential constituent of the primary cell wall, and thereby participates in cell wall construction of growing tissues.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 young developing tissues. Expressed in 7 day old seedlings, roots, nodes bearing flowers, flower buds and siliques.INDUCTION:By auxin and brassinolide.PTM:Contains at least one intrachain disulfide bond essential for its enzymatic activity (By similarity).PTM:N-glycosylated; not essential for its enzymatic activity.SIMILARITY:Belongs to the glycosyl hydrolase 16 family. XTH group 1 subfamily.SEQUENCE CAUTION:Sequence=AAK62373.1; Type=Frameshift; Positions=146;WEB RESOURCE:Name=XTH-World; URL=""http://labs.plantbio.cornell.edu/XTH/""; "
