Glucokinase
This enzyme facilitates phosphorylation of glucose to glucose-6-phosphate. In humans and most other vertebrates glucokinase is used in teh liver, the pancreas, the gut and brain. It plays an important role in regulating carbohydrate metabolism, triggering shifts in the cell in response to glucose level: glucokinase is a sort of a glucose sensor. It only phosphorylates glucose if its concetnration is high enough. The structure of glucokinase reveals an allosteric site through which small molecules may modulate the kinetic properties of the enzyme; a property that is the basis for using the enzyme when treating type 2 diabetes.

The glucokinase has 18 (unless we counted wrong), 13 (this one is for sure), and 3 : a , amide or MRK in short, and last a sugar (alpha-d-glucose) or simply GLC.
