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(More)
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. In(More)
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(More)
Evidence is presented indicating that the carrier-mediated uptake of 3-deoxy-2-oxo-D-gluconate and D-glucuronate in Escherichia coli K12 is driven by the deltapH and deltapsi components of the protonmotive force. 1. Approximately two protons enter the cells with each sugar molecule, independent of the sugar and the strain used. 2. In respiring cells, the(More)
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(More)
