| Calcium Binding | |
| catalytic Activity | CATALYTIC ACTIVITY: Reaction=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.; EC=2.4.1.207; Evidence={ECO:0000250|UniProtKB:Q38857}; |
| DNA Binding | |
| EC Number | 2.4.1.207 |
| Enzyme Function | FUNCTION: 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). {ECO:0000250|UniProtKB:Q38857}. |
