[[http://www.uniprot.org/uniprot/HXK4_HUMAN HXK4_HUMAN]] Catalyzes the initial step in utilization of glucose by the beta-cell and liver at physiological glucose concentration. Glucokinase has a high Km for glucose, and so it is effective only when glucose is abundant. The role of GCK is to provide G6P for the synthesis of glycogen. Pancreatic glucokinase plays an important role in modulating insulin secretion. Hepatic glucokinase helps to facilitate the uptake and conversion of glucose by acting as an insulin-sensitive determinant of hepatic glucose usage.

== Publication Abstract from PubMed ==
Guided by co-crystal structures of compounds 15, 22 and 30, an SBDD approach led to the discovery of the 6-methyl pyridone series as a novel class of GKAs that potently activate GK in enzyme and cell assays. Anti-diabetic OGTT efficacy was demonstrated with 54 in a mouse model of type 2 diabetes.
