DESCRIPTION

Also known as XXT1_ARATH, XXT1, XT1. Xylosyltransferase specific to UDP-D-xylose that accepts both cellopentaose and cellohexaose as substrates, with a better use of cellohexaose, to produce xyloglucan. Adds preferentially the first xylosyl residue to the fourth glucosyl residue from the reducing end of both acceptors. Transfer one xylose mainly to the second glucose residue from the non-reducing end. The acceptor should have a minimum of four glucose residues. Forms homodimer (PubMed:29784804). Interacts with XXT2 (PubMed:22665445).
