Activity summary

Phosphoglucomutase 2 also known as PGM2 is an enzyme involved in carbohydrate metabolism. It catalyzes the reversible conversion of glucose-1-phosphate to glucose-6-phosphate an essential step in glycogenesis and glycogenolysis. PGM2 has a mass of about 65 kDa and is expressed in various tissues including liver muscle and brain. It is often expressed in cells that require significant amounts of energy due to its role in glucose utilization.

Biological function summary

PGM2 functions to maintain cellular energy balance by supporting glycogen storage and breakdown. It operates as an individual enzyme not being part of any multi-enzyme complex but it significantly impacts glucose flux within cells. The enzyme plays a role in both anabolic and catabolic processes highlighting its importance in energy homeostasis. Adequate functioning of PGM2 ensures that cells have access to glucose during fasting or between meals vital for processes like muscle contraction and brain function.

Pathways

PGM2 is actively involved in the glycogen metabolism pathway and interacts with key enzymes like glycogen phosphorylase and glycogen synthase. Its enzymatic activity links it to pathways such as glycolysis where glucose-6-phosphate serves as a substrate. Through its role in glucose conversion PGM2 influences the availability of substrate for additional enzymes in glycolysis and glycogenesis impacting energy production and storage in cells.

Associated diseases and disorders

Defects in PGM2 have been associated with glycogen storage disease which affects glucose and glycogen metabolism leading to energy production issues. It is also observed in metabolic myopathies where disordered energy metabolism leads to muscle weakness and fatigue. PGM2 interacts with glycogen phosphorylase in these disorders as both play parts in the conversion of glucose-1-phosphate to glucose-6-phosphate implicating their coordination in maintaining metabolic stability.
