Structural basis for allosteric regulation of the monomeric allosteric enzyme human glucokinase.
K.Kamata, M.Mitsuya, T.Nishimura, J.Eiki, Y.Nagata.
Glucokinase is a monomeric enzyme that displays a low affinity for glucose and a sigmoidal saturation curve for its substrate, two properties that are important for its playing the role of a glucose sensor in pancreas and liver. The molecular basis for these two properties is not well understood. Herein we report the crystal structures of glucokinase in its active and inactive forms, which demonstrate that global conformational change, including domain reorganization, is induced by glucose binding. This suggests that the positive cooperativity of monomeric glucokinase obeys the "mnemonical mechanism" rather than the well-known concerted model. These structures also revealed an allosteric site through which small molecules may modulate the kinetic properties of the enzyme. This finding provided the mechanistic basis for activation of glucokinase as a potential therapeutic approach for treating type 2 diabetes mellitus.

Figure 6.
Figure 6. Kinetic Model of GlucokinaseGlucokinase appears to exist in three conformations and to have two catalytic cycles. The ratio of two catalytic cycles is responsible for the sigmoidal response to glucose. Although ordered process in the slow cycle of glucokinase was indicated by isotope-exchange experiment, the addition of substrates in the fast cycle may be random.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
