Phosphorolysis reaction
WebPhosphorylases are a special group of non-Leloir-type glycosyltransferases that catalyze the phosphorylysis of the glycosidic bond at the nonreducing end, releasing a sugar 1-phosphate residue.10 Since the reaction is reversible, these enzymes are also used to carry out the glycosylation reaction using sugar-1-phosphate as the donor. WebOct 16, 2007 · Phosphorylase activity was determined by measuring the amount of glucose-1-P formed from phosphorolysis of the substrate, as described in Materials and Methods. For each reaction 400 μg of partial acid-hydrolyzed CβG was used as substrate.
