Fluorescence probes are useful in studies of protein conformation and interactions because of the availability of fluorophors with a variety of fluorescence properties, of derivatives with different labeling specificities, and because of the accessibility of excellent fluorescence instruments (Haugland, 1992; Lakowicz, 1983). Derivatives of the fluorophor can be attached to specific amino acid residues of proteins while maintaining the spectroscopic properties of the parent chromophore. Information about the protein domain to which the probe is attached can be obtained because the sensitive fluorescence properties depend on the nature of the excited state. Due to the more polar electron distribution in the excited state than the ground state, the probe can interact strongly with the immediate environment, allowing for the use of a variety of fluorescence measurements:(I) the spectral characteristics depend on the polarity of the immediate environment;(2) the relative quantum yield or intensity depends on the proximity of quenching groups;(3) changes in relative probe exposure can be obtained by solute quenching techniques;(4) as fluorescence energy'donors and
