Xyloglucan endotransglucosylase

From Wikipedia, the free encyclopedia

Xyloglucan endotransglucosylase (XET) is an apoplastic enzyme found across the plant kingdom. The enzyme catalyzes the endotransglucosylation of two xyloglucan polysaccharides, effectively 'stitching' them together.[1]

Function in planta[edit]

XET is thought to promote cell expansion by breaking the xyloglucan cross-links between cellulose microfibrils before reforming them, potentially now linked to another microfibril.
