Structural highlights
FunctionTHM1_THADA Taste-modifying protein; intensely sweet-tasting. It is 100000 times sweeter than sucrose on a molar basis. Publication Abstract from PubMedThe X-ray structure of the adduct formed in the reaction between the gold N-heterocyclic carbene compound Au(NHC)Cl (with NHC = 1-butyl-3-methyl-imidazole-2-ylidene) and the model protein thaumatin is reported here. The structure reveals binding of Au(NHC)+ fragments to distinct protein sites. Notably, binding of the gold compound occurs at lysine side chains and at the N-terminal tail; the metal binds the protein after releasing Cl- ligand, but retaining NHC fragment.
