Mechanism for Fluorescence Quenching of Tryptophan by Oxamate and Pyruvate: Conjugation and Solvation-Induced Photoinduced Electron Transfer

Oxamate and pyruvate are isoelectronic molecules. They both quench tryptophan fluorescence with Stern–Volmer constants of 16 and 20 M(−1), respectively, which are comparable to that of arcrylamide, a commonly used probe for protein structure. On the other hand, it is well known that neither the carb...
