A novel fluorescent probe for protein binding and folding studies: p-cyano-phenylalanine.

Recently, it is has been shown that the C=N stretching vibration of a non-natural amino acid, p-cyano-phenylalanine (PheCN), could be used as an infrared reporter of local environment. Here, we further showed that the fluorescence emission of PheCN is also sensitive to solvent and, therefore, could ... View More
