Abstract: "Atomic force microscopy (AFM) compression simulation" approach together with "CASSCF/AM1 ONIOM" model calculation method is used for investigating the quenching mechanism of the luminescence in green fluorescent protein (GFP). Our results show that the electronic properties and steric conformations of the chromophore's neighboring residues strongly influence the photo decay behaviors in GFP.
