WebHexokinase-1 (HK1) is an enzyme that in humans is encoded by the HK1 gene on chromosome 10. Hexokinases phosphorylate glucose to produce glucose-6-phosphate (G6P), the first step in most glucose metabolism pathways. This gene encodes a ubiquitous form of hexokinase which localizes to the outer membrane of mitochondria. WebHexokinases are intracellular enzymes that phosphorylate glucose, mannose and fructose to the corresponding hexose 6-phosphates. The resulting phosphate esters can then be broken down to pyruvate by glycolysis or used for different biosynthesis. Hexokinases play an important role in the control of glycolysis.
