Crystal structure of glycogen phosphorylase complexed with an anthranilimide based inhibitor GSK055
Structural highlights
DiseasePYGL_HUMAN Defects in PYGL are the cause of glycogen storage disease type 6 (GSD6) [MIM:232700. A metabolic disorder characterized by mild to moderate hypoglycemia, mild ketosis, growth retardation, and prominent hepatomegaly. Heart and skeletal muscle are not affected.[1] FunctionPYGL_HUMAN Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedKey binding interactions of the anthranilimide based glycogen phosphorylase a (GPa) inhibitor 2 from X-ray crystallography studies are described. This series of compounds bind to the AMP site of GP. Using the binding information the core and the phenyl urea moieties were optimized. This work culminated in the identification of compounds with single nanomolar potency as well as in vivo efficacy in a diabetic model. Anthranilimide based glycogen phosphorylase inhibitors for the treatment of type 2 diabetes.
