2.4.1.207

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.
