Phosphorylase - an overview ScienceDirect Topics

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. WebMar 1, 2024 · Although various DSPs reported, their reaction mechanisms can be boiled down to three types as Fig. 1 shows [ 25 ]. The majority of DSPs are inverting enzymes that follow a single displacement mechanism ( Fig. 1 A), catalyzing a direct nucleophilic attack of phosphate on the anomeric carbon.
