Application
Use Hexokinase for the determination of D-glucose, D-fructose, and D-sorbitol in food or biological research samples. Hexokinase may also be used for the assay of other saccharides, which are convertible to glucose or fructose, and is, therefore, useful in the assay of many glycosides.
Hexokinase has been used in the enzymatic detection of nitric oxide and in the measurement of ATP by luminescence method
Biochem/physiol Actions
Hexokinase catalyzes the conversion of hexoses to hexose-6-phosphate in an ATP-dependent manner. It is also called as the glycolytic enzyme as it catalyzes the first step in glucose metabolism with the formation of glucose-6-phosphate (G6P). In eukaryotes, it functions as a glucose sensor.
General description
ATP:D-hexose 6-phosphotransferase
Hexokinase consists of 486 amino acids and has a molecular weight of 57,000 D (SDS-PAGE) in citrate/phosphate buffer. It may form dimers under other buffer conditions.
