donor xyloglucan + acceptor xyloglucan acceptors: polymer xyloglucan or its derived oligosaccharides Populus alba ?
-
 ?
donor xyloglucan + acceptor xyloglucan acceptors: XXXG-ol, a reduced xyloglucan heptasaccharide, its dimer XXXGXXXG-ol, and other xyloglucan oligosaccharides, reaction probably involves an enzyme-donor-acceptor complex, in which the enzyme has two binding sites separately for donor and acceptor, mechanism Populus alba ?

donor xyloglucan + acceptor xyloglucan highly specific for xyloglucan as the glycosyl donor Populus alba ?

 ?
donor xyloglucan + Xylalpha(1-6)Glcbeta(1-4)(Xylalpha(1-6))Glcbeta(1-4)(Xylalpha(1-6))Glcbeta(1-4)Glc-ol transfers a part of xyloglucan to the reduced xyloglucan heptasaccharide XXXG-ol, the acceptor acts by combining with the enzyme independently of the donor, the velocity of the reaction decreases gradually as the heptasaccharide unit is increased from two to four, the affinity for XXXG-ol is increased at a higher concentration of donor xyloglucan Populus alba ?
