GFP is a chromoprotein, that absorbs in the blue and green range of the spectrum and
shows a strong green fluorescence. Unlike all other chromoproteins,
the chromophore is just the oxidation product of 3 adjacent
aminoacids. For this reason, GFP has become a very important marker in
biochemistry and microbiology during the past years.
It also shows a photodynamics and photochemistry interesting in its own right.
That was my motivation to do research on the properties of GFP and its chromophore during
the past years. I utilized spectroscopic methods, particularly time resolved spectroscopy,
resonance Raman spectroscopy and hole-burning spectroscopy to investigate the protein and
its chromophore.
