In vitro synthesis of particulate glycogen from uridine diphosphate glucose. III. Some properties of the product synthesized by muscle glycogen synthetase

High molecular weight glycogen has been prepared in vitro with muscle glycogen synthetase (uridine diphosphate glucose: α-1,4-glucan α-4-glucosyltransferase, EC 2.4.1.11) and liver or muscle branching enzyme (α-1,4-glucan: α-1,4-glucan 6-glycosyltransferase, EC 2.4.1.18) with uridine diphosphate glu...
