Three-dimensional structure of thaumatin I, an intensely sweet protein.
Thaumatin and monellin are the two sweetest compounds known to man--about 100,000 times sweeter than sugar on a molar basis and 3000 times on a weight basis. These proteins represent a unique class of proteins that are taste-active. We report the three-dimensional structure of thaumatin I at 3.1 A resolution.
