IUBMB Enzyme Nomenclature


Accepted name: xyloglucan:xyloglucosyl transferase

Reaction: breaks a β-(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

Other name(s): endo-xyloglucan transferase; xyloglucan endotransglycosylase

Systematic name: xyloglucan:xyloglucan xyloglucanotransferase

Comments: does not use cello-oligosaccharides as either donor or acceptor.
