Diagrammatic representation of the T1R2-T1R3 receptor showing possible stabilization by binding of a sweet protein to a secondary binding site on the surface of free form II. The sweet protein is represented in red on the left part of free form II, preventing it reverting to free form I. (adapted from references 52 and 54)
