  2. Hexokinase - Wikipedia

    en.wikipedia.org/wiki/Hexokinase

    A hexokinase is an enzyme that irreversibly phosphorylates hexoses (six-carbon sugars), forming hexose phosphate. In most organisms, glucose is the most important substrate for hexokinases, and glucose-6-phosphate is the most important product.

  3. Hexokinase I - Wikipedia

    en.wikipedia.org/wiki/Hexokinase_I

    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 ...

  4. Hexokinase II - Wikipedia

    en.wikipedia.org/wiki/Hexokinase_II

    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.

  5. Phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Phosphorylation

    [clarification needed] The hexokinase enzyme has a low Michaelis constant (K m), indicating a high affinity for glucose, so this initial phosphorylation can proceed even when glucose levels at nanoscopic scale within the blood.

  6. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    An enzyme is fully specified by four numerical designations. For example, hexokinase (EC 2.7.1.1) is a transferase (EC 2) that adds a phosphate group (EC 2.7) to a hexose sugar, a molecule containing an alcohol group (EC 2.7.1). [21] Sequence similarity. EC categories do not reflect sequence similarity. For instance, two ligases of the same EC ...

  8. Kinase - Wikipedia

    en.wikipedia.org/wiki/Kinase

    Mutations in the hexokinase gene can lead to a hexokinase deficiency which can cause nonspherocytic hemolytic anemia. [27] Phosphofructokinase, or PFK, catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate and is an important point in the regulation of glycolysis. High levels of ATP, H +, and citrate inhibit PFK. If ...
