thaumatin

A 207-amino acid heterodimeric protein, produced by the African fruit katemfe (Thaumatococcus danielli), which, like monellin, is a sweet protein that binds specifically to taste receptors. Thaumatin elicits a sensation of sweetness 100,000 times sweeter than sugar on a molar basis, given that it has a greater affinity than dextrose for the sweet taste receptor.
