Glycogen synthase expression of the muscle isozyme and not the liver isozyme. However, muscle-specific glycogen synthase activation may lead to excessive accumulation of glycogen, leading to damage in the heart and central nervous system following ischemic insults. The reaction is highly regulated by allosteric effectors such as glucose-6-phosphate (activator) and by phosphorylation reactions (deactivating). Glucose-6-phosphate allosteric activating action allows glycogen synthase to operate as a glucose-6-phosphate sensor. The inactivating phosphorylation is triggered by the hormone glucagon, which is secreted by the pancreas in response to decreased blood glucose levels. The enzyme also cleaves the ester bond between the C1 position of glucose
Wanamaker Organ This level of dedication was maintained when corporate parentage shifted from the Wanamaker family to Carter Hawley Hale Stores followed by Woodward & Lothrop, The May Department Stores Company, Lord & Taylor, and finally to Macy's. The Wanamaker Organ was originally built by the Los Angeles Art Organ Company, successors to the Murray M. Harris Organ Co., for the 1904 St. Louis World's Fair. It was designed to be the largest organ in the world, an imitation of a full-size orchestra with particularly complete resources of full organ tone including mixtures. In addition to its console, the organ was originally
