Isolation and partial characterization of two forms of rat heart glycogen phosphorylase.

Properties and functions of the storage sites of glycogen phosphorylase.

It is demonstrated that the GP catalytic sites are active even in the presence of CDs, and that the actions of the catalytic site and the storage site are independent of each other.

Glycogen synthase I from human polymorphonuclear leukocytes was phosphorylated with cAMP dependent protein kinase, synthase kinase or phosvitin kinase prepared from these cells, with results concluded that the initial kinetic changes were dependent on phosphorylation of c-A, which contained two sites, one for each kinase.

Enzymes regulating glycogen metabolism in swine subcutaneous adipose tissue. I. Phosphorylase and phosphorylase phosphatase.

Several lines of evidence suggest that AMP inhibition was due to an action on the substrate rather than on the enzyme, suggesting that phosphorylase kinase in homogenates of swine adipose tissue is present largely in an activated form.

The interaction of liver phosphorylase a with glucose and AMP.

Results indicate that the stimulation of the phosphorylase phosphatase reaction by glucose is secondary to the binding of the hexose to phosphorus a, and that this binding is modulated by the concentration of AMP.

Glycogen phosphorylase and its converter enzymes in haemolysates of normal human subjects and of patients with type VI glycogen-storage disease. A study of phosphorylase kinase deficiency.

The activity of phosphorylase kinase was measured in haemolysates obtained from a series of patients who had been classified as suffering from type VI glycogenosis, with an almost complete deficiency of phosphate kinase observed in the haEMolysate and in the liver.
