General annotation (Comments)

Function

May catalyze xyloglucan endohydrolysis (XEH) and/or endotransglycosylation (XET). 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.

Subcellular location

Secretedcell wall Probable. Secretedextracellular spaceapoplast Probable.

Post-translational modification

Contains at least one intrachain disulfide bond essential for its enzymatic activity By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 16 family. XTH group 2 subfamily.
