Protein

Probable xyloglucan endotransglucosylase/hydrolase protein 30

Gene

XTH30

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -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).By similarity

Miscellaneous

In contrast to group 1 and group 2 endotransglucosylase/hydrolase proteins, it may not contain the ligase activity, and may catalyze endohydrolysis xyloglucan polymers only.

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.
