Protein
Probable xyloglucan endotransglucosylase/hydrolase protein 31
Gene
XTH31, ATXG, XTR8, At3g44990, F14D17.60
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Catalyzes 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 activityi

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.
