The active conformation of human glucokinase is not altered by allosteric activators.

Glucokinase (GK) catalyses the formation of glucose 6-phosphate from glucose and ATP. A specific feature of GK amongst hexokinases is that it can cycle between active and inactive conformations as a function of glucose concentration, resulting in a unique positive kinetic cooperativity with glucose, which turns GK into a unique key sensor of glucose metabolism, notably in the pancreas. GK is a target of antidiabetic drugs aimed at the activation of GK activity, leading to insulin secretion.

Crystal structure of Apis mellifera OBP14, a C-minus odorant-binding protein, and its complexes with odorant molecules.

Apis mellifera (Amel) relies on its olfactory system to detect and identify new-sources of floral food. The Odorant-Binding Proteins (OBPs) are the first proteins involved in odorant recognition and interaction, before activation of the olfactory receptors. The Amel genome possess a set of 21 OBPs, much fewer compared to the 60-70 OBPs found in Diptera genomes.

The crystal structure of odorant binding protein 7 from Anopheles gambiae exhibits an outstanding adaptability of its binding site.

Anopheles gambiae (Agam) targets human and animals by using its olfactory system, leading to the spread of Plasmodium falciparum, the malaria vector. Odorant binding proteins (OBPs) participate to the first event in odorant recognition and constitute an interesting target for insect control. OBPs interact with olfactory receptors to which they deliver the odorant molecule.

Crystal structure of a novel type of odorant-binding protein from Anopheles gambiae, belonging to the C-plus class.

Agam (Anopheles gambiae) relies on its olfactory system to target human prey, leading eventually to the injection of Plasmodium falciparum, the malaria vector. OBPs (odorant-binding proteins) are the first line of proteins involved in odorant recognition. They interact with olfactory receptors and thus constitute an interesting target for insect control.
