Protein

Xyloglucan endotransglucosylase/hydrolase protein 9

Gene

XTH9

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. Involved in internodal cell elongation.1 Publication

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.

Expressioni

Tissue specificityi

Highly expressed in shoot apices. In the vegetative and reproductive phases, it accumulates in the shoot apex region, where cell division is most active. In the reproductive phase, it is also expressed in flower buds, flower stalks and internodes bearing flowers.2 Publications
