Pathway: Disease (Homo sapiens)
Biological processes are captured in Reactome by identifying the molecules (DNA, RNA, protein, small molecules) involved in them and describing the details of their interactions. From this molecular viewpoint, human disease pathways have three mechanistic causes: the inclusion of microbially-expressed proteins, altered functions of human proteins, or changed expression levels of otherwise functionally

Pathway: Metabolism (Homo sapiens)
Metabolic processes in human cells generate energy through the oxidation of molecules consumed in the diet and mediate the synthesis of diverse essential molecules not taken in the diet as well as the inactivation and elimination of toxic ones generated endogenously or present in the extracellular environment. The processes of energy metabolism can be classified into two groups according to whether the

Pathway: Metabolism of carbohydrates (Homo sapiens)
These pathways together are responsible for: 1) the extraction of energy and carbon skeletons for biosyntheses from dietary sugars and related molecules; 2) the short-term storage of glucose in the body (as glycogen) and its mobilization during a short fast; and 3) the synthesis of glucose from pyruvate during extended fasts

Pathway: Myoclonic epilepsy of Lafora (Homo sapiens)
Lafora disease is a progressive neurodegenerative disorder with onset typically late in childhood, characterized by seizures and progressive neurological deterioration and death within ten years of onset. Recessive mutations in EPM2A (laforin) and NHLRC1 (malin) have been identified as causes of the disease. The disease is classified here as one of glycogen storage as EPM2A (laforin) and NHLRC1 (malin)

Pathway: Glycogen storage diseases (Homo sapiens)
The regulated turnover of glycogen plays a central, tissue-specific role in the maintenance of blood glucose levels and in the provision of glucose to tissues such as muscle and brain in response to stress. Defects in the enzymes involved in glycogen turnover are associated with abnormal responses to fasting and exercise that can differ widely in their presentation and severity. Additional symptoms can

Reaction: glycogen phosphorylase (PYGL) dimer b + 2 ATP => glycogen phosphorylase (PYGL) dimer a + 2 ADP (Homo sapiens)
The cytosolic phosphorylase kinase complex catalyzes the phosphorylation of glycogen phosphorylase ( ... annotated here, consisting of four copies each of PHKA2 (alpha regulatory) (van den Berg et al. 1995), PHKB (beta regulatory) (Burwinkel et al. 2003a), PHKG2 (gamma catalytic) (Burwinkel et al. 2003b; Maichele et al. 2006) and CALM (calmodulin) subunits is abundant in liver and its action on the for ...

Pathway: Glycogen breakdown (glycogenolysis) (Homo sapiens)
Cytosolic glycogen breakdown occurs via the same chemical steps in all tissues but is separately regulated via tissue specific isozymes and signaling pathways that enable distinct physiological fates for liver glycogen and that in other tissues. Glycogen phosphorylase, which can be activated by phosphorylase kinase, catalyzes the removal of glucose residues as glucose 1-phosphate from the ends of glyco

Pathway: Glucose metabolism (Homo sapiens)
Glucose is the major form in which dietary sugars are made available to cells of the human body. Its breakdown is a major source of energy for all cells, and is essential for the brain and red blood cells. Glucose utilization begins with its uptake by cells and conversion to glucose 6-phosphate, which cannot traverse the cell membrane. Fates open to cytosolic glucose 6-phosphate include glycolysis to y

Reaction: glycogen phosphorylase (PYGB) dimer b + 2 ATP => glycogen phosphorylase (PYGB) dimer a + 2 ADP (Homo sapiens)
The phosphorylation of glycogen phosphorylase PYGB by the widely expressed form of the phosphorylase kinase complex is inferred from its activity on PGYM (Newgard et al. 1989)
