In molecular biology, the xyloglucan endo-transglycosylase (XET) is an enzyme that is involved in the metabolism of xyloglucan, which is a component of plant cell walls. This enzyme is part of glycoside hydrolase family 16.
Xyloglucan endo-transglycosylase C terminal domain
Xyloglucan endo-transglycosylase (XET) is thought to be highly important during seed germination, fruit ripening, and rapid wall expansion.[1]
Xyloglucan is the predominant hemicellulose in the primary cell walls of most dicotyledons. With cellulose, it forms a network that strengthens the cell wall. XET catalyses the splitting of xyloglucan chains and the linking of the newly generated reducing end to the non-reducing end of another xyloglucan chain, thereby loosening the cell wall.[2]
