Coupling enzyme of hexokinase

WebWe identified a regulatory pathway involving ΔNp63 and the glycolytic enzyme hexokinase 2 (HK2). ΔNp63 direct-dependent regulation of HK2 expression contributes to the coupling between glucose metabolism and oxidative phosphorylation, providing the energy necessary to sustain cell proliferation and protecting cells from oxidative stress. WebWhat is the purpose of hexokinase? Hexokinase is the initial enzyme of glycolysis, catalyzing the phosphorylation of glucose by ATP to glucose-6-P. It is one of the rate-limiting enzymes of glycolysis. Its activity declines rapidly as normal red cells age. What is the coupling enzyme used in hexokinase method?
