Glucose-6-phosphatase deficiency
Glucose-6-phosphatase deficiency (G6P deficiency), or glycogen storage disease type I (GSDI), is a group of inherited metabolic diseases, including types Ia and Ib, characterized by poor tolerance to fasting, growth retardation and hepatomegaly resulting from accumulation of glycogen and fat in the liver. Prevalence is unknown and annual incidence is around 1/100,000 births. GSDIa is the more f...
متن کاملGlucose-6-phosphatase in normal adult human intestinal mucosa.
1. The existence of specific glucose-6-phosphatase activity in human intestinal mucosa has been somewhat controversial. 2. We have demonstrated the presence of low levels of specific glucose-6-phosphatase activity in normal human adult intestinal mucosa. Activity was found in oesophagus, stomach, duodenum and colon. 3. Immunoblot analysis using antibodies monospecific for the 36.5 kDa liver glu...
متن کاملThe glucose-6-phosphatase system.
Glucose-6-phosphatase (G6Pase), an enzyme found mainly in the liver and the kidneys, plays the important role of providing glucose during starvation. Unlike most phosphatases acting on water-soluble compounds, it is a membrane-bound enzyme, being associated with the endoplasmic reticulum. In 1975, W. Arion and co-workers proposed a model according to which G6Pase was thought to be a rather unsp...
متن کاملLiver Microsomal Glucose 6 - Phosphatase , Inorganic Pyrophosphatase , and Pyrophosphate - Glucose
Recently, we (1) described experiments which strongly supported the common identity of glucose 6-phosphatase,’ inorganic pyrophosphatase, pyrophosphate-glucose phosphotransferase, and mannose B-phosphate-glucose phosphotransferase activities present in a preparation obtained by ammonium sulfate fractionation of deoxycholate-dispersed rat liver microsomes. Previously, Segal, Washko, and Lee (2, ...
متن کاملGlucose regulates in vivo glucose-6-phosphatase gene expression in the liver of diabetic rats.
Overproduction of glucose by the liver is the major cause of fasting hyperglycemia in both insulin-dependent and non-insulin-dependent diabetes mellitus. The distal enzymatic step in the process of glucose output is catalyzed by the glucose-6-phosphatase complex. We show here that 90% partially pancreatectomized diabetic rats have a >5-fold increase in the messenger RNA and a 3-4-fold increase ...
