概要 This study found that neoculin changed pH-dependently in its tryptophan- and ANS-derived fluorescence spectra, while no such change occurred in a neoculin variant whose histidine residues were replaced with alanine. These results suggest that the sweetness of neoculin depends on structural change accompanying the pH change, with the histidine residues playing a key role.
