Activity summary

H6PD also known as glucose dehydrogenase (GDH) or G.D.H. is an enzyme with an important mechanical role in cellular metabolism. It has a molecular mass of approximately 92 kDa. This enzyme participates in the reversible oxidation of glucose and other hexose sugars an action that results in the generation of NADPH. H6PD is expressed mainly in the endoplasmic reticulum of various tissues including liver adrenal gland and adipose tissue where it facilitates the pentose phosphate pathway and other metabolic functions.

Biological function summary

H6PD influences multiple metabolic processes by maintaining cellular redox balance through NADPH production. It plays a role in carbohydrate metabolism and aids in lipid biosynthesis and detoxification processes. Although H6PD does not form a complex it works closely with 11β-hydroxysteroid dehydrogenase type 1 an enzyme involved in corticosteroid metabolism. This interaction supports the regulation of local cortisol concentrations via the interconversion of active and inactive forms.

Pathways

Several metabolic pathways integrate the function of H6PD including the pentose phosphate pathway and the gluconeogenesis pathway. In the pentose phosphate pathway H6PD contributes to the generation of ribose-5-phosphate a precursor for nucleotide synthesis. Related proteins like glucose-6-phosphate dehydrogenase (G6PD) also share roles in these pathways working together to ensure the proper supply of reducing agents like NADPH needed for anabolic reactions.

Associated diseases and disorders

H6PD has associations with metabolic disorders such as cortisone reductase deficiency and type 2 diabetes. Its role in cortisone metabolism connects it closely with 11β-hydroxysteroid dehydrogenase type 1 which can lead to deregulation of corticosteroid activity and contribute to insulin resistance and obesity. Understanding the connections between H6PD function and metabolic syndrome aids in revealing the complex landscape of metabolic control and its clinical implications.
