WebApr 11, 2024 · (1) Background: A low-FODMAP diet is often recommended in the treatment of irritable bowel syndrome, but it does not improve abdominal symptoms in all patients, and an alternative diet is desirable. The purpose of this study was to evaluate the efficacy of a low-FODMAP diet with a concomitant reduction in tryptophan (TRP) intake in irritable … We engineered and expressed 27 different single-tryptophan mutants of ubiquitin, with tryptophan located at 75% of the most solvent-accessible positions (Fig. 2a). We first monitored the equilibrium unfolding transitions of all 27 single-tryptophan ubiquitin mutants using tryptophan fluorescence spectroscopy, … See more We then used fluorescence intensities for the 27 tryptophan probes to characterize the structure of the IL (Fig. 4). The fluorescence intensity of tryptophan is … See more Three tryptophan mutations also generated sufficient destabilization in the IL (ΔΔGU-I > 4 kJ mol−1) to allow characterization of the extent to which these mutated … See more
