Protein
Probable xyloglucan endotransglucosylase/hydrolase protein 11
Gene
XTH11, At3g48580, T8P19.90
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

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 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.

Caution

In contrast to other xyloglucan endotransglucosylase proteins, the catalytic motif is atypical and lacks the proton donor site. It therefore may not be functional in vivo.
