Ketohexokinase

The HKH gene is spliced to HKH-A and the more active HKH-C. KHK acts in the first step of fructose metabolism. Disease HKH deficiency causes the essential fructosuria disorder. Structural highlights Human KHK inhibitor interacts with the 2 monomers. Water molecule shown as red sphere.
