The article offers information on the structural basis of sugar recognition by insect sweet taste receptors, focusing on Drosophila sugar receptors GR43a and GR64a. Topics include the formation of sugar-gated cation channels by GR43a and GR64a; the structural features of these receptors; and the mechanism of sugar binding and channel opening.
