Hexokinase I/A is found in all mammalian tissues, and is considered a "housekeeping enzyme," unaffected by most physiological, hormonal, and metabolic changes. Hexokinase II/B constitutes the principal regulated isoenzyme in many cell types and is increased in many cancers. It is the hexokinase found in muscle and heart.
Hexokinase III, also known as hexokinase C, is an enzyme which in humans is encoded by the Hk3 gene on chromosome 5. [ 5 ] [ 6 ] Hexokinases phosphorylate glucose to produce glucose-6-phosphate , the first step in most glucose metabolism pathways.
Hexokinase has a large induced fit motion that closes over the substrates adenosine triphosphate and xylose. Binding sites in blue, substrates in black and Mg 2+ cofactor in yellow. (The different mechanisms of substrate binding. The classic model for the enzyme-substrate interaction is the induced fit model. [3]
Hexokinase II, also known as Hexokinase B and HK2, is an enzyme which in humans is encoded by the HK2 gene on chromosome 2. [5] [6] Hexokinases phosphorylate glucose to produce glucose 6-phosphate, the first step in most glucose metabolism pathways. Hexokinase II is the predominant hexokinase form found in skeletal muscle.
Pokémon Go (stylized as Pokémon GO) is a 2016 augmented reality (AR) mobile game, part of the Pokémon franchise, developed and published by Niantic in collaboration with Nintendo and The Pokémon Company for iOS and Android devices.

Hexokinase I, also known as hexokinase A and 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 ...
Hexokinase is inhibited by high levels of G6P in the cell. Thus the rate of entry of glucose into cells partially depends on how fast G6P can be disposed of by glycolysis, and by glycogen synthesis (in the cells which store glycogen, namely liver and muscles). [33] [35] Glucokinase, unlike hexokinase, is not inhibited by G6P. It occurs in liver ...
