Green Fluorescent Protein Proteopedia, life in 3D.
Roger Tsien and co-workers were intrigued by the absence of a necessary cofactor and began to research the structure of GFP and how it relates to its fluorescence. They discovered that a helix within the beta barrel structure of GFP actually contained a fluorophore responsible for fluorescence.

Des protéines fluorescentes sont dérivées de la GFP et possèdent des propriétés physiques différentes, qui leur permettent de fluorescer dans d'autres' couleurs. Le prix Nobel de chimie a été attribué à ses découvreurs, en 2008. Intéressé par ce que vous venez de lire?
Plasmids 101: Green Fluorescent Protein GFP.
Posted by Marcy Patrick on May 15, 2014 113300: AM. Bioluminescence and fluorescence from proteins such as Green Fluorescent Protein GFP has likely existed in creatures such as jellyfish for millions of years; however, it took until the 1960s for scientists to begin to study GFP and deduce its biochemical properties.
Green Fluorescent Protein The Embryo Project Encyclopedia. Green Fluorescent Protein.
In a 2002 paper, Chalfie and his colleagues describe how they first labeled a specific gene involved in tactile perception in neuron cells with GFP, and then observed the amount of fluorescence emitted by those cells. Because mutant cells produced less or more GFP than normal cells, the abnormal amount of fluorescence production indicated the abnormal development of mutants.
Green Fluorescent Protein: A Molecular Microscope.
Proteins are extremely small and cannot be seen, even under an electron microscope. However, if one could somehow link GFP to a specific protein, one would be able to see the green fluorescence of the GFP that is attached to the protein.
GFP Structure.
This structural information sheds new light the work of Inouye and Tsuji 10, who found that GFP fluorescence is reversibly lost upon reduction with strong reducing agents such as sodium dithionite, but not upon treatment with weaker reducing agents known to reduce disulfide bonds, such as beta-mercaptoethanol BME, dithiothreitol DTT or reduced glutathione GSSG.
