Regulation of glucose 6 phosphate dehydrogenase activity in rat liver tissue by insulin and hydrocortisone


Voprosy Meditsinskoi Khimii 26(2): 169-174
Regulation of glucose 6 phosphate dehydrogenase activity in rat liver tissue by insulin and hydrocortisone
Activity of partially purified glucose-6-phosphate dehydrogenase (G6PD), its isoenzyme spectrum and kinetic properties were studied in liver tissue of intact rats as well as in animals treated with insulin and hydrocortisone. The activation and inhibition of G6PD by insulin and hydrocortisone are due most likely not to alterations in conformation of the enzymatic molecules, but to the opposite influence of these hormones on the content of the main fraction of the isoenzyme spectrum of G6PD, which accounts for 78-90% of its total activity.
