Sensing pH via p-Cyanophenylalanine Fluorescence: Application to Determine Peptide pK(a) and Membrane-Penetration Kinetics

We expand the spectroscopic utility of a well-known infrared and fluorescence probe, p-cyanophenylalanine, by showing that it can also serve as a pH sensor. This new application is based on the notion that the fluorescence quantum yield of this unnatural amino acid, when placed at or near the N-term...
