Effects of glucose on glycogen synthetase, phosphorylase, and glycogen deposition in the perfused rat liver.
An increase in the perfusate glucose concentration from near zero to about 11 mM increased glycogen synthesis in the perfused, isolated rat liver from zero to a value about half the maximum seen in the intact animal. Increased synthesis appeard to due not only to provision of substrate but also to conversion of glycogen synthetase to the active form and of glycogen phosphorylase to the inactive...
متن کاملLiver Glycogen Phosphorylase Kinase
Liver glycogen phosphorylase kinase was assayed by measuring the radioactivity of [y-32P]ATP incorporated into rabbit skeletal muscle phosphorylase b. Using this assay two forms of phosphorylase kinase, Kinase I and Kinase II, were pirified about 70and 130-fold, respectively, from rabbit liver cytosol by DEAE-Sephadex A50 column chromatography, ammonium sulfate fractionation, gel filtration on ...
متن کاملGlycogen Phosphorylase in DictyosteLium discoideum
The glycogen phosphorylase of Dictyostelium discoideum has been purified over 200-fold from cells in the culmination stage of development. Analytical gel electrophoresis of the purified enzyme indicates one major protein band with a molecular weight of approximately 210,000. Gel elution verified the presence of phosphorylase activity associated with the protein band. Electrophoresis of partiall...
متن کاملAdipose Tissue Glycogen Synthetase
In vitro activation of adipose tissue glycogen synthetase caused a change in kinetic properties of the enzyme. The nonactivated enzyme had a K, for UDP-glucose of 2 m when measured without glucose-6-P. The K, decreased to 0.7 mM in the presence of 2 mM glucose-6-P. The K, for UDP-glucose of the activated enzyme was 0.8 mM. Glucose-6-P affected both the K, for UDP-glucose and the v m&x of the no...
متن کاملHepatic glycogen synthetase deficiency
In the 13 years since hepatic glycogen synthetase deficiency was first described in identical twins no further cases seem to have been observed. We report a child who had suffered from occasional morning convulsions since the age of 7. Three 24-hour metabolic profiles showed fasting hypoglycaemia, hyperketonaemia, but normal lactate. Hyperglycaemia and hyperlactataemia occurred after meals. Glu...
