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. WebThe histidine phosphocarrier protein (HPr) kinase/phosphorylase (HPrK/P) modulates the phosphorylation state of the HPr protein, and it is involved in the use of carbon sources by Gram-positive bacteria. Its X-ray structure, as concluded from crystals of proteins from several species, is a hexamer; however, there are no studies about its conformational …
