WebJun 24, 2024 · In addition to fluorescent proteins, there is a group of GFP-like colored chromoproteins that are not fluorescent. In chromoproteins, the chromophore’s Tyr residue as a rule is in the trans protonated state stabilized by H-bonds with amino acid residues of the immediate neighborhood. WebAt this point, GFP does not fluoresce (Heim et al., 1994) but, con-ditional on the presence of molecular oxygen, the α–β bond of residue 66 is subsequently dehydrogenated into conjugation with the imidazolinone (Fig. 4, bottom, right), which results in maturation of the GFP chromophore to its fluorescent form (Heim et al., 1994; Cubitt et
