The characterization of the stoichiometry of oligomerizing proteins is still a non-trivial challenge. In this study, the stoichiometry of coiled-coil peptides was determined via green fluorescent protein (GFP) fusion proteins and fluorescence anisotropy. This thesis thus provides the framework for the reliable differentiation between monomer, dimer, trimer, and higher oligomer. When studying photobleached GFP fusion proteins, we further found that the irradiation of GFP with blue high-intensity light leads to the fragmentation of GFP at residue 65 and therefore to the degradation of the protein.
