In enzymology, a xyloglucan:xyloglucosyl transferase (EC 2.4.1.207) is an enzyme that catalyzes the chemical reaction in which a beta-(1,4) bond in the backbone of a xyloglucan in broken; the xyloglucanyl segment is then transferred to the O4 of the non-reducing terminal glucose residue of either xyloglucan or an oligosaccharide thereof.[1]
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is xyloglucan:xyloglucan xyloglucanotransferase. Other names in common use include endo-xyloglucan transferase, and xyloglucan endotransglycosylase.
Structural studiesedit
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1UMZ and 1UN1.
