Discovery of the green fluorescent protein (GFP) and consequently its mutants was the beginning of a new era in protein labelling and provided an alternative to existing markers. Mutations were designed in yellow fluorescent protein (S65G/V68L/S72A/T203Y) to change the solvent accessibility (H148G) and to modify polar groups (H148Q, E222Q) near the chromophore. The green fluorescent protein (GFP) from the jellyfish Aequorea victoria has emerged as an important reporter molecule for monitoring gene expression and protein localization in vivo and in real time ( 1–5).Unlike other bioluminescent reporters, the chromophore in GFP is intrinsic to the primary structure of the protein, and GFP fluorescence does not require substrates or other co-factors ( 1). This reality derives from the complexity of the photophysics of most fluorescent molecules—complexity that reveals the imperfections of available theory.
