ABSTRACT
The electronic spectra of the chromophore of the wild type green fluorescent protein, GFP, and of a mutant form Y66F GFP in which the chromophore lacks the hydroxyl group have been studied. The acid-base properties, solvatochromism, vibronic structure and edge excitation red shift have all been measured. The results are compared with the spectra of the chromophore in the protein environment. These data suggest that the transition energy for the GFP chromophore is influenced by a number of factors in its environment, and in particular by hydrogen bonding.
